Steps to Calculate GCD of 76, 30, 64, 69 using LCM Formula
Given numbers are 76, 30, 64, 69
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(76, 30) = 1140
GCD(76, 30) = ( 76 x 30 ) / 1140
= 76 / 30
= 76
Step2:
LCM(2, 64) = 64
GCD(2, 64) = ( 2 x 64 ) / 64
= 2 / 64
= 2
Step3:
LCM(2, 69) = 138
GCD(2, 69) = ( 2 x 69 ) / 138
= 2 / 69
= 2
So, Greatest Common Divisor of 76, 30, 64, 69 is 1
