Given numbers are 355, 778, 640, 532

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 778 are 2 x 389

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

Prime factors of 532 are 2 x 2 x 7 x 19

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

Given numbers are 355, 778, 640, 532

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

Apply this formula for all numbers.

Step1:

LCM(355, 778) = 276190

GCD(355, 778) = ( 355 x 778 ) / 276190

= 355 / 778

= 355

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

So, Greatest Common Divisor of 355, 778, 640, 532 is 1
