Given numbers are 420, 647, 510, 427
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 647 are 647
Prime factors of 510 are 2 x 3 x 5 x 17
Prime factors of 427 are 7 x 61
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 647, 510, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 647) = 271740
GCD(420, 647) = ( 420 x 647 ) / 271740
= 420 / 647
= 420
Step2:
LCM(1, 510) = 510
GCD(1, 510) = ( 1 x 510 ) / 510
= 1 / 510
= 1
Step3:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
So, Greatest Common Divisor of 420, 647, 510, 427 is 1
