Steps to Calculate GCD of 427, 686, 478, 212 using LCM Formula
Given numbers are 427, 686, 478, 212
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 686) = 41846
GCD(427, 686) = ( 427 x 686 ) / 41846
= 427 / 686
= 427
Step2:
LCM(7, 478) = 3346
GCD(7, 478) = ( 7 x 478 ) / 3346
= 7 / 478
= 7
Step3:
LCM(1, 212) = 212
GCD(1, 212) = ( 1 x 212 ) / 212
= 1 / 212
= 1
So, Greatest Common Divisor of 427, 686, 478, 212 is 1
