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 404 are 2 x 2 x 101
Prime factors of 671 are 11 x 61
Prime factors of 210 are 2 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 780, 404, 671, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 404) = 78780
GCD(780, 404) = ( 780 x 404 ) / 78780
= 780 / 404
= 780
Step2:
LCM(4, 671) = 2684
GCD(4, 671) = ( 4 x 671 ) / 2684
= 4 / 671
= 4
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 780, 404, 671, 210 is 1
