Given numbers are 678, 998, 695, 631

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

Apply this formula for all numbers.

Step1:

LCM(678, 998) = 338322

GCD(678, 998) = ( 678 x 998 ) / 338322

= 678 / 998

= 678

Step2:

LCM(2, 695) = 1390

GCD(2, 695) = ( 2 x 695 ) / 1390

= 2 / 695

= 2

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 678, 998, 695, 631 is 1
