Given numbers are 651, 621, 889, 249

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

Apply this formula for all numbers.

Step1:

LCM(651, 621) = 134757

GCD(651, 621) = ( 651 x 621 ) / 134757

= 651 / 621

= 651

Step2:

LCM(3, 889) = 2667

GCD(3, 889) = ( 3 x 889 ) / 2667

= 3 / 889

= 3

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 651, 621, 889, 249 is 1
