Steps to Calculate GCD of 115, 518, 72, 681 using LCM Formula
Given numbers are 115, 518, 72, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 518) = 59570
GCD(115, 518) = ( 115 x 518 ) / 59570
= 115 / 518
= 115
Step2:
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
= 1 / 72
= 1
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 115, 518, 72, 681 is 1
