Given numbers are 248, 136, 392, 457

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

Apply this formula for all numbers.

Step1:

LCM(248, 136) = 4216

GCD(248, 136) = ( 248 x 136 ) / 4216

= 248 / 136

= 248

Step2:

LCM(8, 392) = 392

GCD(8, 392) = ( 8 x 392 ) / 392

= 8 / 392

= 8

Step3:

LCM(8, 457) = 3656

GCD(8, 457) = ( 8 x 457 ) / 3656

= 8 / 457

= 8

So, Greatest Common Divisor of 248, 136, 392, 457 is 1
