14
Solution: The GCF of 140 and 28 is 14.
What is the HCF of 140?
The HCF of 140 and 196 is 28. To calculate the Highest common factor (HCF) of 140 and 196, we need to factor each number (factors of 140 = 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140; factors of 196 = 1, 2, 4, 7, 14, 28, 49, 98, 196) and choose the highest factor that exactly divides both 140 and 196, i.e., 28.
What is the HCF of 28?
The HCF of 28 and 32 is 4. To calculate the HCF (Highest Common Factor) of 28 and 32, we need to factor each number (factors of 28 = 1, 2, 4, 7, 14, 28; factors of 32 = 1, 2, 4, 8, 16, 32) and choose the highest factor that exactly divides both 28 and 32, i.e., 4.
What is the HCF of 28 and 144?
So the greatest common factor 28 and 144 is 4.
What are factors of 140?
Solution: The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70 and 140.
How do you find the HCF?
How to Find HCF?
- Step 1: Write each number as a product of its prime factors. This method is called here prime factorization.
- Step 2: Now list the common factors of both the numbers.
- Step 3: The product of all common prime factors is the HCF ( use the lower power of each common factor)
What is the Highest common factor of 28 and 16?
So, H.C.F of 16 and 28 is 4.

What are the factors of 140?
Who wrote multiplication table?
The multiplication table is sometimes attributed to the ancient Greek mathematician Pythagoras (570–495 BC).
How do I find the HCF of a number?
How is HCF calculated?
The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.
How do you find highest common factor?
For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.
What are two factors for 140?
The pairs of numbers that when multiplied together make 140 are the factors of 140. 1 × 140, 2 × 70 , 4 × 35 , 5 × 28 , 7 × 20, 10 × 14 are the pairs that make 140 and they are all the factors of 140.
