Steps to Calculate GCD of 87, 13, 17, 79 using LCM Formula
Given numbers are 87, 13, 17, 79
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(87, 13) = 1131
GCD(87, 13) = ( 87 x 13 ) / 1131
= 87 / 13
= 87
Step2:
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
= 1 / 17
= 1
Step3:
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
= 1 / 79
= 1
So, Greatest Common Divisor of 87, 13, 17, 79 is 1
