Given numbers are 631, 781, 990, 673

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

Apply this formula for all numbers.

Step1:

LCM(631, 781) = 492811

GCD(631, 781) = ( 631 x 781 ) / 492811

= 631 / 781

= 631

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 673) = 673

GCD(1, 673) = ( 1 x 673 ) / 673

= 1 / 673

= 1

So, Greatest Common Divisor of 631, 781, 990, 673 is 1
