Given numbers are 169, 303, 642

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

Apply this formula for all numbers.

Step1:

LCM(169, 303) = 51207

GCD(169, 303) = ( 169 x 303 ) / 51207

= 169 / 303

= 169

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 169, 303, 642 is 1
