Steps to Calculate GCD of 631, 509, 651, 400 using LCM Formula

Given numbers are 631, 509, 651, 400

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

Apply this formula for all numbers.

Step1:

LCM(631, 509) = 321179

GCD(631, 509) = ( 631 x 509 ) / 321179

= 631 / 509

= 631


Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1


Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1


So, Greatest Common Divisor of 631, 509, 651, 400 is 1
