Steps to Calculate GCD of 59, 88, 68, 21 using LCM Formula
Given numbers are 59, 88, 68, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(59, 88) = 5192
GCD(59, 88) = ( 59 x 88 ) / 5192
= 59 / 88
= 59
Step2:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 59, 88, 68, 21 is 1
