Given numbers are 248, 328, 630, 790

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

Apply this formula for all numbers.

Step1:

LCM(248, 328) = 10168

GCD(248, 328) = ( 248 x 328 ) / 10168

= 248 / 328

= 248

Step2:

LCM(8, 630) = 2520

GCD(8, 630) = ( 8 x 630 ) / 2520

= 8 / 630

= 8

Step3:

LCM(2, 790) = 790

GCD(2, 790) = ( 2 x 790 ) / 790

= 2 / 790

= 2

So, Greatest Common Divisor of 248, 328, 630, 790 is 2
