Steps to Calculate GCD of 83, 38, 26, 21 using LCM Formula
Given numbers are 83, 38, 26, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(83, 38) = 3154
GCD(83, 38) = ( 83 x 38 ) / 3154
= 83 / 38
= 83
Step2:
LCM(1, 26) = 26
GCD(1, 26) = ( 1 x 26 ) / 26
= 1 / 26
= 1
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 83, 38, 26, 21 is 1
