Given numbers are 642, 965, 404

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

Apply this formula for all numbers.

Step1:

LCM(642, 965) = 619530

GCD(642, 965) = ( 642 x 965 ) / 619530

= 642 / 965

= 642

Step2:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 642, 965, 404 is 1
