The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 454, 311, 220, 477
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 311) = 141194
GCD(454, 311) = ( 454 x 311 ) / 141194
= 454 / 311
= 454
Step2:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
Step3:
LCM(1, 477) = 477
GCD(1, 477) = ( 1 x 477 ) / 477
= 1 / 477
= 1
So, Greatest Common Divisor of 454, 311, 220, 477 is 1
