Given numbers are 642, 889, 818, 603

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

Apply this formula for all numbers.

Step1:

LCM(642, 889) = 570738

GCD(642, 889) = ( 642 x 889 ) / 570738

= 642 / 889

= 642

Step2:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 642, 889, 818, 603 is 1
