Steps to Calculate GCD of 911, 638, 56, 430 using LCM Formula
Given numbers are 911, 638, 56, 430
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(911, 638) = 581218
GCD(911, 638) = ( 911 x 638 ) / 581218
= 911 / 638
= 911
Step2:
LCM(1, 56) = 56
GCD(1, 56) = ( 1 x 56 ) / 56
= 1 / 56
= 1
Step3:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
So, Greatest Common Divisor of 911, 638, 56, 430 is 1
