Steps to Calculate GCD of 81, 35, 76, 56 using LCM Formula
Given numbers are 81, 35, 76, 56
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(81, 35) = 2835
GCD(81, 35) = ( 81 x 35 ) / 2835
= 81 / 35
= 81
Step2:
LCM(1, 76) = 76
GCD(1, 76) = ( 1 x 76 ) / 76
= 1 / 76
= 1
Step3:
LCM(1, 56) = 56
GCD(1, 56) = ( 1 x 56 ) / 56
= 1 / 56
= 1
So, Greatest Common Divisor of 81, 35, 76, 56 is 1
