Given numbers are 872, 644, 173, 772

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

Apply this formula for all numbers.

Step1:

LCM(872, 644) = 140392

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

= 872 / 644

= 872

Step2:

LCM(4, 173) = 692

GCD(4, 173) = ( 4 x 173 ) / 692

= 4 / 173

= 4

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 872, 644, 173, 772 is 1
