Given numbers are 648, 638, 619, 875

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

Apply this formula for all numbers.

Step1:

LCM(648, 638) = 206712

GCD(648, 638) = ( 648 x 638 ) / 206712

= 648 / 638

= 648

Step2:

LCM(2, 619) = 1238

GCD(2, 619) = ( 2 x 619 ) / 1238

= 2 / 619

= 2

Step3:

LCM(1, 875) = 875

GCD(1, 875) = ( 1 x 875 ) / 875

= 1 / 875

= 1

So, Greatest Common Divisor of 648, 638, 619, 875 is 1
