Given numbers are 249, 255, 730, 356

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

Apply this formula for all numbers.

Step1:

LCM(249, 255) = 21165

GCD(249, 255) = ( 249 x 255 ) / 21165

= 249 / 255

= 249

Step2:

LCM(3, 730) = 2190

GCD(3, 730) = ( 3 x 730 ) / 2190

= 3 / 730

= 3

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 249, 255, 730, 356 is 1
