Steps to Calculate GCD of 67, 21, 51, 83 using LCM Formula
Given numbers are 67, 21, 51, 83
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(67, 21) = 1407
GCD(67, 21) = ( 67 x 21 ) / 1407
= 67 / 21
= 67
Step2:
LCM(1, 51) = 51
GCD(1, 51) = ( 1 x 51 ) / 51
= 1 / 51
= 1
Step3:
LCM(1, 83) = 83
GCD(1, 83) = ( 1 x 83 ) / 83
= 1 / 83
= 1
So, Greatest Common Divisor of 67, 21, 51, 83 is 1
