168

The GCF is 14.

The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 140 are 2, 2, 5, and 7. The prime factors of 168 are 2, 2, 2, 3, and 7. The prime factors they have in common are 2, 2, and 7, so their greatest common factor is 2 x 2 x 7 = 28. Another way to approach this is to look at the difference between 140 and 168, which is 28. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. Since both 140 and 168 are divisible by 28, the greatest common factor is 28.

The greatest common factor of 24, 84, 168 is 12.

Try to factor this number. Look for small factors first - numbers like 2, 3, 5, 7. That is, try whether your number is divisible by such numbers. Once you find such a factor, divide the number by your factor to get the other factor.

The GCF is 7.

168

Factor means a number times another numbers equals a larger number. Since 7 can be called "a number" and 168 is the "larger number" then the "another number" would be something the multiplys by 7 to equal 168. That number would be 24

7 as in 7x16=112 7x24=168 and 7x9=63

The GCF is 7.

240xy-192x-210y+168 = 6(8x - 7)(5y - 4)

5 x 7 = 35

Since 24 is a factor of 168, it is automatically the GCF. The GCF of 24 and 168 is 24. This leaves 1 and 7 from division respectively. This cannot be reduced further with any common factors.

No, it's a multiple. 84 is a factor of 168.
