Steps to Calculate GCD of 93, 83, 21, 12 using LCM Formula
Given numbers are 93, 83, 21, 12
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(93, 83) = 7719
GCD(93, 83) = ( 93 x 83 ) / 7719
= 93 / 83
= 93
Step2:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
Step3:
LCM(1, 12) = 12
GCD(1, 12) = ( 1 x 12 ) / 12
= 1 / 12
= 1
So, Greatest Common Divisor of 93, 83, 21, 12 is 1
