Given numbers are 420, 657, 566, 787
The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 657 are 3 x 3 x 73
Prime factors of 566 are 2 x 283
Prime factors of 787 are 787
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 657, 566, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 657) = 91980
GCD(420, 657) = ( 420 x 657 ) / 91980
= 420 / 657
= 420
Step2:
LCM(3, 566) = 1698
GCD(3, 566) = ( 3 x 566 ) / 1698
= 3 / 566
= 3
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 420, 657, 566, 787 is 1
