Given numbers are 865, 963, 642

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

Apply this formula for all numbers.

Step1:

LCM(865, 963) = 832995

GCD(865, 963) = ( 865 x 963 ) / 832995

= 865 / 963

= 865

Step2:

LCM(1, 642) = 642

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

= 1 / 642

= 1

So, Greatest Common Divisor of 865, 963, 642 is 1
