Steps to Calculate GCD of 41, 70, 80, 42 using LCM Formula
Given numbers are 41, 70, 80, 42
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(41, 70) = 2870
GCD(41, 70) = ( 41 x 70 ) / 2870
= 41 / 70
= 41
Step2:
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
= 1 / 80
= 1
Step3:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
So, Greatest Common Divisor of 41, 70, 80, 42 is 1
