Steps to Calculate GCD of 691, 315, 130, 310 using LCM Formula

Given numbers are 691, 315, 130, 310

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(691, 315) = 217665

GCD(691, 315) = ( 691 x 315 ) / 217665

= 691 / 315

= 691


Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1


Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1


So, Greatest Common Divisor of 691, 315, 130, 310 is 1
