Steps to Calculate GCD of 85, 23, 91, 80 using LCM Formula
Given numbers are 85, 23, 91, 80
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(85, 23) = 1955
GCD(85, 23) = ( 85 x 23 ) / 1955
= 85 / 23
= 85
Step2:
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
= 1 / 91
= 1
Step3:
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
= 1 / 80
= 1
So, Greatest Common Divisor of 85, 23, 91, 80 is 1
