Steps to Calculate GCD of 38, 91, 40, 51 using LCM Formula
Given numbers are 38, 91, 40, 51
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(38, 91) = 3458
GCD(38, 91) = ( 38 x 91 ) / 3458
= 38 / 91
= 38
Step2:
LCM(1, 40) = 40
GCD(1, 40) = ( 1 x 40 ) / 40
= 1 / 40
= 1
Step3:
LCM(1, 51) = 51
GCD(1, 51) = ( 1 x 51 ) / 51
= 1 / 51
= 1
So, Greatest Common Divisor of 38, 91, 40, 51 is 1
