Given numbers are 620, 166, 521, 721
The list of prime factors of all numbers are
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 166 are 2 x 83
Prime factors of 521 are 521
Prime factors of 721 are 7 x 103
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 620, 166, 521, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 166) = 51460
GCD(620, 166) = ( 620 x 166 ) / 51460
= 620 / 166
= 620
Step2:
LCM(2, 521) = 1042
GCD(2, 521) = ( 2 x 521 ) / 1042
= 2 / 521
= 2
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 620, 166, 521, 721 is 1
