Steps to Calculate GCD of 142, 521, 138, 311 using LCM Formula
Given numbers are 142, 521, 138, 311
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 521) = 73982
GCD(142, 521) = ( 142 x 521 ) / 73982
= 142 / 521
= 142
Step2:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
Step3:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
So, Greatest Common Divisor of 142, 521, 138, 311 is 1
