Given numbers are 518, 658, 631, 778

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

Apply this formula for all numbers.

Step1:

LCM(518, 658) = 24346

GCD(518, 658) = ( 518 x 658 ) / 24346

= 518 / 658

= 518

Step2:

LCM(14, 631) = 8834

GCD(14, 631) = ( 14 x 631 ) / 8834

= 14 / 631

= 14

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 518, 658, 631, 778 is 1
