Steps to Calculate GCD of 76, 77, 85, 61 using LCM Formula
Given numbers are 76, 77, 85, 61
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(76, 77) = 5852
GCD(76, 77) = ( 76 x 77 ) / 5852
= 76 / 77
= 76
Step2:
LCM(1, 85) = 85
GCD(1, 85) = ( 1 x 85 ) / 85
= 1 / 85
= 1
Step3:
LCM(1, 61) = 61
GCD(1, 61) = ( 1 x 61 ) / 61
= 1 / 61
= 1
So, Greatest Common Divisor of 76, 77, 85, 61 is 1
