Steps to Calculate GCD of 75, 39, 68, 76 using LCM Formula
Given numbers are 75, 39, 68, 76
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(75, 39) = 975
GCD(75, 39) = ( 75 x 39 ) / 975
= 75 / 39
= 75
Step2:
LCM(3, 68) = 204
GCD(3, 68) = ( 3 x 68 ) / 204
= 3 / 68
= 3
Step3:
LCM(1, 76) = 76
GCD(1, 76) = ( 1 x 76 ) / 76
= 1 / 76
= 1
So, Greatest Common Divisor of 75, 39, 68, 76 is 1
