Given numbers are 438, 156, 535, 634

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 535 are 5 x 107

Prime factors of 634 are 2 x 317

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

Given numbers are 438, 156, 535, 634

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

Apply this formula for all numbers.

Step1:

LCM(438, 156) = 11388

GCD(438, 156) = ( 438 x 156 ) / 11388

= 438 / 156

= 438

Step2:

LCM(6, 535) = 3210

GCD(6, 535) = ( 6 x 535 ) / 3210

= 6 / 535

= 6

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 438, 156, 535, 634 is 1
