Steps to Calculate GCD of 18, 85, 80, 59 using LCM Formula
Given numbers are 18, 85, 80, 59
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(18, 85) = 1530
GCD(18, 85) = ( 18 x 85 ) / 1530
= 18 / 85
= 18
Step2:
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
= 1 / 80
= 1
Step3:
LCM(1, 59) = 59
GCD(1, 59) = ( 1 x 59 ) / 59
= 1 / 59
= 1
So, Greatest Common Divisor of 18, 85, 80, 59 is 1
