Given numbers are 250, 945, 280, 128

The list of prime factors of all numbers are

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 250, 945, 280, 128

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(250, 945) = 47250

GCD(250, 945) = ( 250 x 945 ) / 47250

= 250 / 945

= 250

Step2:

LCM(5, 280) = 280

GCD(5, 280) = ( 5 x 280 ) / 280

= 5 / 280

= 5

Step3:

LCM(5, 128) = 640

GCD(5, 128) = ( 5 x 128 ) / 640

= 5 / 128

= 5

So, Greatest Common Divisor of 250, 945, 280, 128 is 1
