Given numbers are 420, 481, 671, 417
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 481 are 13 x 37
Prime factors of 671 are 11 x 61
Prime factors of 417 are 3 x 139
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 481, 671, 417
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 481) = 202020
GCD(420, 481) = ( 420 x 481 ) / 202020
= 420 / 481
= 420
Step2:
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
= 1 / 671
= 1
Step3:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
So, Greatest Common Divisor of 420, 481, 671, 417 is 1
