Steps to Calculate GCD of 315, 328, 42, 691 using LCM Formula
Given numbers are 315, 328, 42, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 328) = 103320
GCD(315, 328) = ( 315 x 328 ) / 103320
= 315 / 328
= 315
Step2:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 315, 328, 42, 691 is 1
