Given numbers are 348, 129, 947, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(348, 129) = 14964
GCD(348, 129) = ( 348 x 129 ) / 14964
= 348 / 129
= 348
Step2:
LCM(3, 947) = 2841
GCD(3, 947) = ( 3 x 947 ) / 2841
= 3 / 947
= 3
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 348, 129, 947, 921 is 1
