Steps to Calculate GCD of 139, 212, 309, 812 using LCM Formula
Given numbers are 139, 212, 309, 812
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 212) = 29468
GCD(139, 212) = ( 139 x 212 ) / 29468
= 139 / 212
= 139
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 812) = 812
GCD(1, 812) = ( 1 x 812 ) / 812
= 1 / 812
= 1
So, Greatest Common Divisor of 139, 212, 309, 812 is 1
