Steps to Calculate GCD of 68, 81, 31, 52 using LCM Formula
Given numbers are 68, 81, 31, 52
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(68, 81) = 5508
GCD(68, 81) = ( 68 x 81 ) / 5508
= 68 / 81
= 68
Step2:
LCM(1, 31) = 31
GCD(1, 31) = ( 1 x 31 ) / 31
= 1 / 31
= 1
Step3:
LCM(1, 52) = 52
GCD(1, 52) = ( 1 x 52 ) / 52
= 1 / 52
= 1
So, Greatest Common Divisor of 68, 81, 31, 52 is 1
