Given numbers are 687, 582, 628, 225

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

Apply this formula for all numbers.

Step1:

LCM(687, 582) = 133278

GCD(687, 582) = ( 687 x 582 ) / 133278

= 687 / 582

= 687

Step2:

LCM(3, 628) = 1884

GCD(3, 628) = ( 3 x 628 ) / 1884

= 3 / 628

= 3

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 687, 582, 628, 225 is 1
