Given numbers are 623, 855, 638, 250

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

Apply this formula for all numbers.

Step1:

LCM(623, 855) = 532665

GCD(623, 855) = ( 623 x 855 ) / 532665

= 623 / 855

= 623

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

So, Greatest Common Divisor of 623, 855, 638, 250 is 1
