Steps to Calculate GCD of 39, 52, 70, 81 using LCM Formula
Given numbers are 39, 52, 70, 81
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(39, 52) = 156
GCD(39, 52) = ( 39 x 52 ) / 156
= 39 / 52
= 39
Step2:
LCM(13, 70) = 910
GCD(13, 70) = ( 13 x 70 ) / 910
= 13 / 70
= 13
Step3:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
So, Greatest Common Divisor of 39, 52, 70, 81 is 1
