Steps to Calculate GCD of 812, 947, 42, 291 using LCM Formula
Given numbers are 812, 947, 42, 291
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 947) = 768964
GCD(812, 947) = ( 812 x 947 ) / 768964
= 812 / 947
= 812
Step2:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
Step3:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
So, Greatest Common Divisor of 812, 947, 42, 291 is 1
