Given numbers are 642, 989, 874, 249

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

Apply this formula for all numbers.

Step1:

LCM(642, 989) = 634938

GCD(642, 989) = ( 642 x 989 ) / 634938

= 642 / 989

= 642

Step2:

LCM(1, 874) = 874

GCD(1, 874) = ( 1 x 874 ) / 874

= 1 / 874

= 1

Step3:

LCM(1, 249) = 249

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

= 1 / 249

= 1

So, Greatest Common Divisor of 642, 989, 874, 249 is 1
