Given numbers are 647, 396, 756, 248

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

Apply this formula for all numbers.

Step1:

LCM(647, 396) = 256212

GCD(647, 396) = ( 647 x 396 ) / 256212

= 647 / 396

= 647

Step2:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 647, 396, 756, 248 is 1
