Given numbers are 249, 685, 63, 976

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

Apply this formula for all numbers.

Step1:

LCM(249, 685) = 170565

GCD(249, 685) = ( 249 x 685 ) / 170565

= 249 / 685

= 249

Step2:

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

= 1 / 63

= 1

Step3:

LCM(1, 976) = 976

GCD(1, 976) = ( 1 x 976 ) / 976

= 1 / 976

= 1

So, Greatest Common Divisor of 249, 685, 63, 976 is 1
