Steps to Calculate GCD of 44, 78, 65, 47 using LCM Formula
Given numbers are 44, 78, 65, 47
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(44, 78) = 1716
GCD(44, 78) = ( 44 x 78 ) / 1716
= 44 / 78
= 44
Step2:
LCM(2, 65) = 130
GCD(2, 65) = ( 2 x 65 ) / 130
= 2 / 65
= 2
Step3:
LCM(1, 47) = 47
GCD(1, 47) = ( 1 x 47 ) / 47
= 1 / 47
= 1
So, Greatest Common Divisor of 44, 78, 65, 47 is 1
