Given numbers are 247, 513, 498, 255

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

Apply this formula for all numbers.

Step1:

LCM(247, 513) = 6669

GCD(247, 513) = ( 247 x 513 ) / 6669

= 247 / 513

= 247

Step2:

LCM(19, 498) = 9462

GCD(19, 498) = ( 19 x 498 ) / 9462

= 19 / 498

= 19

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 247, 513, 498, 255 is 1
