The list of prime factors of all numbers are
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 277 are 277
Prime factors of 805 are 5 x 7 x 23
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 620, 277, 805, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 277) = 171740
GCD(620, 277) = ( 620 x 277 ) / 171740
= 620 / 277
= 620
Step2:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 620, 277, 805, 634 is 1
