Steps to Calculate GCD of 36, 81, 83, 21 using LCM Formula
Given numbers are 36, 81, 83, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(36, 81) = 324
GCD(36, 81) = ( 36 x 81 ) / 324
= 36 / 81
= 36
Step2:
LCM(9, 83) = 747
GCD(9, 83) = ( 9 x 83 ) / 747
= 9 / 83
= 9
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 36, 81, 83, 21 is 1
