Given numbers are 640, 535, 179, 280

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 535 are 5 x 107

Prime factors of 179 are 179

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

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

Given numbers are 640, 535, 179, 280

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

Apply this formula for all numbers.

Step1:

LCM(640, 535) = 68480

GCD(640, 535) = ( 640 x 535 ) / 68480

= 640 / 535

= 640

Step2:

LCM(5, 179) = 895

GCD(5, 179) = ( 5 x 179 ) / 895

= 5 / 179

= 5

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 640, 535, 179, 280 is 1
