Given numbers are 249, 879, 786, 355

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

Apply this formula for all numbers.

Step1:

LCM(249, 879) = 72957

GCD(249, 879) = ( 249 x 879 ) / 72957

= 249 / 879

= 249

Step2:

LCM(3, 786) = 786

GCD(3, 786) = ( 3 x 786 ) / 786

= 3 / 786

= 3

Step3:

LCM(3, 355) = 1065

GCD(3, 355) = ( 3 x 355 ) / 1065

= 3 / 355

= 3

So, Greatest Common Divisor of 249, 879, 786, 355 is 1
