Steps to Calculate GCD of 342, 687, 86, 581 using LCM Formula
Given numbers are 342, 687, 86, 581
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(342, 687) = 78318
GCD(342, 687) = ( 342 x 687 ) / 78318
= 342 / 687
= 342
Step2:
LCM(3, 86) = 258
GCD(3, 86) = ( 3 x 86 ) / 258
= 3 / 86
= 3
Step3:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
So, Greatest Common Divisor of 342, 687, 86, 581 is 1
