The list of prime factors of all numbers are
Prime factors of 156 are 2 x 2 x 3 x 13
Prime factors of 152 are 2 x 2 x 2 x 19
Prime factors of 634 are 2 x 317
Prime factors of 621 are 3 x 3 x 3 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 156, 152, 634, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 152) = 5928
GCD(156, 152) = ( 156 x 152 ) / 5928
= 156 / 152
= 156
Step2:
LCM(4, 634) = 1268
GCD(4, 634) = ( 4 x 634 ) / 1268
= 4 / 634
= 4
Step3:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
So, Greatest Common Divisor of 156, 152, 634, 621 is 1
