Steps to Calculate GCD of 78, 84, 35, 51 using LCM Formula
Given numbers are 78, 84, 35, 51
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(78, 84) = 1092
GCD(78, 84) = ( 78 x 84 ) / 1092
= 78 / 84
= 78
Step2:
LCM(6, 35) = 210
GCD(6, 35) = ( 6 x 35 ) / 210
= 6 / 35
= 6
Step3:
LCM(1, 51) = 51
GCD(1, 51) = ( 1 x 51 ) / 51
= 1 / 51
= 1
So, Greatest Common Divisor of 78, 84, 35, 51 is 1
