Given numbers are 631, 610, 87, 781

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

Apply this formula for all numbers.

Step1:

LCM(631, 610) = 384910

GCD(631, 610) = ( 631 x 610 ) / 384910

= 631 / 610

= 631

Step2:

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

= 1 / 87

= 1

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 631, 610, 87, 781 is 1
