Steps to Calculate GCD of 681, 857, 81, 159 using LCM Formula
Given numbers are 681, 857, 81, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 857) = 583617
GCD(681, 857) = ( 681 x 857 ) / 583617
= 681 / 857
= 681
Step2:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 681, 857, 81, 159 is 1
