Steps to Calculate GCD of 644, 872, 757, 504 using LCM Formula

Given numbers are 644, 872, 757, 504

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

Apply this formula for all numbers.

Step1:

LCM(644, 872) = 140392

GCD(644, 872) = ( 644 x 872 ) / 140392

= 644 / 872

= 644


Step2:

LCM(4, 757) = 3028

GCD(4, 757) = ( 4 x 757 ) / 3028

= 4 / 757

= 4


Step3:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1


So, Greatest Common Divisor of 644, 872, 757, 504 is 1
