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

Apply this formula for all numbers.

Step1:

LCM(168, 916) = 38472

GCD(168, 916) = ( 168 x 916 ) / 38472

= 168 / 916

= 168

Step2:

LCM(4, 390) = 780

GCD(4, 390) = ( 4 x 390 ) / 780

= 4 / 390

= 4

Step3:

LCM(2, 248) = 248

GCD(2, 248) = ( 2 x 248 ) / 248

= 2 / 248

= 2

So, Greatest Common Divisor of 168, 916, 390, 248 is 2
