Given numbers are 355, 530, 278, 637

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 530 are 2 x 5 x 53

Prime factors of 278 are 2 x 139

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 355, 530, 278, 637

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

Apply this formula for all numbers.

Step1:

LCM(355, 530) = 37630

GCD(355, 530) = ( 355 x 530 ) / 37630

= 355 / 530

= 355

Step2:

LCM(5, 278) = 1390

GCD(5, 278) = ( 5 x 278 ) / 1390

= 5 / 278

= 5

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 355, 530, 278, 637 is 1
