Given numbers are 249, 417, 656, 755

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

Apply this formula for all numbers.

Step1:

LCM(249, 417) = 34611

GCD(249, 417) = ( 249 x 417 ) / 34611

= 249 / 417

= 249

Step2:

LCM(3, 656) = 1968

GCD(3, 656) = ( 3 x 656 ) / 1968

= 3 / 656

= 3

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 249, 417, 656, 755 is 1
