Steps to Calculate GCD of 155, 819, 313, 631 using LCM Formula

Given numbers are 155, 819, 313, 631

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

Apply this formula for all numbers.

Step1:

LCM(155, 819) = 126945

GCD(155, 819) = ( 155 x 819 ) / 126945

= 155 / 819

= 155


Step2:

LCM(1, 313) = 313

GCD(1, 313) = ( 1 x 313 ) / 313

= 1 / 313

= 1


Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1


So, Greatest Common Divisor of 155, 819, 313, 631 is 1
