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

Apply this formula for all numbers.

Step1:

LCM(856, 448) = 47936

GCD(856, 448) = ( 856 x 448 ) / 47936

= 856 / 448

= 856

Step2:

LCM(8, 436) = 872

GCD(8, 436) = ( 8 x 436 ) / 872

= 8 / 436

= 8

Step3:

LCM(4, 630) = 1260

GCD(4, 630) = ( 4 x 630 ) / 1260

= 4 / 630

= 4

So, Greatest Common Divisor of 856, 448, 436, 630 is 2
