Steps to Calculate GCD of 80, 38, 55, 39 using LCM Formula
Given numbers are 80, 38, 55, 39
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(80, 38) = 1520
GCD(80, 38) = ( 80 x 38 ) / 1520
= 80 / 38
= 80
Step2:
LCM(2, 55) = 110
GCD(2, 55) = ( 2 x 55 ) / 110
= 2 / 55
= 2
Step3:
LCM(1, 39) = 39
GCD(1, 39) = ( 1 x 39 ) / 39
= 1 / 39
= 1
So, Greatest Common Divisor of 80, 38, 55, 39 is 1
