The list of prime factors of all numbers are
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
Prime factors of 415 are 5 x 83
Prime factors of 663 are 3 x 13 x 17
Prime factors of 604 are 2 x 2 x 151
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 780, 415, 663, 604
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 415) = 64740
GCD(780, 415) = ( 780 x 415 ) / 64740
= 780 / 415
= 780
Step2:
LCM(5, 663) = 3315
GCD(5, 663) = ( 5 x 663 ) / 3315
= 5 / 663
= 5
Step3:
LCM(1, 604) = 604
GCD(1, 604) = ( 1 x 604 ) / 604
= 1 / 604
= 1
So, Greatest Common Divisor of 780, 415, 663, 604 is 1
