Given numbers are 500, 645, 521, 728
The list of prime factors of all numbers are
Prime factors of 500 are 2 x 2 x 5 x 5 x 5
Prime factors of 645 are 3 x 5 x 43
Prime factors of 521 are 521
Prime factors of 728 are 2 x 2 x 2 x 7 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 500, 645, 521, 728
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(500, 645) = 64500
GCD(500, 645) = ( 500 x 645 ) / 64500
= 500 / 645
= 500
Step2:
LCM(5, 521) = 2605
GCD(5, 521) = ( 5 x 521 ) / 2605
= 5 / 521
= 5
Step3:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
So, Greatest Common Divisor of 500, 645, 521, 728 is 1
