Given numbers are 420, 641, 231, 630
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 641 are 641
Prime factors of 231 are 3 x 7 x 11
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 641, 231, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 641) = 269220
GCD(420, 641) = ( 420 x 641 ) / 269220
= 420 / 641
= 420
Step2:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 420, 641, 231, 630 is 1
