Given numbers are 642, 749, 339, 259

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

Apply this formula for all numbers.

Step1:

LCM(642, 749) = 4494

GCD(642, 749) = ( 642 x 749 ) / 4494

= 642 / 749

= 642

Step2:

LCM(107, 339) = 36273

GCD(107, 339) = ( 107 x 339 ) / 36273

= 107 / 339

= 107

Step3:

LCM(1, 259) = 259

GCD(1, 259) = ( 1 x 259 ) / 259

= 1 / 259

= 1

So, Greatest Common Divisor of 642, 749, 339, 259 is 1
