Given numbers are 768, 248, 689, 631

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

Apply this formula for all numbers.

Step1:

LCM(768, 248) = 23808

GCD(768, 248) = ( 768 x 248 ) / 23808

= 768 / 248

= 768

Step2:

LCM(8, 689) = 5512

GCD(8, 689) = ( 8 x 689 ) / 5512

= 8 / 689

= 8

Step3:

LCM(1, 631) = 631

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

= 1 / 631

= 1

So, Greatest Common Divisor of 768, 248, 689, 631 is 1
