Given numbers are 642, 813, 291, 889

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

Apply this formula for all numbers.

Step1:

LCM(642, 813) = 173982

GCD(642, 813) = ( 642 x 813 ) / 173982

= 642 / 813

= 642

Step2:

LCM(3, 291) = 291

GCD(3, 291) = ( 3 x 291 ) / 291

= 3 / 291

= 3

Step3:

LCM(3, 889) = 2667

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

= 3 / 889

= 3

So, Greatest Common Divisor of 642, 813, 291, 889 is 1
