Given numbers are 249, 372, 220, 117

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

Apply this formula for all numbers.

Step1:

LCM(249, 372) = 30876

GCD(249, 372) = ( 249 x 372 ) / 30876

= 249 / 372

= 249

Step2:

LCM(3, 220) = 660

GCD(3, 220) = ( 3 x 220 ) / 660

= 3 / 220

= 3

Step3:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

So, Greatest Common Divisor of 249, 372, 220, 117 is 1
