Given numbers are 496, 390, 221, 263

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

Apply this formula for all numbers.

Step1:

LCM(496, 390) = 96720

GCD(496, 390) = ( 496 x 390 ) / 96720

= 496 / 390

= 496

Step2:

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

= 2 / 221

= 2

Step3:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1

So, Greatest Common Divisor of 496, 390, 221, 263 is 1
