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

Apply this formula for all numbers.

Step1:

LCM(642, 285) = 60990

GCD(642, 285) = ( 642 x 285 ) / 60990

= 642 / 285

= 642

Step2:

LCM(3, 177) = 177

GCD(3, 177) = ( 3 x 177 ) / 177

= 3 / 177

= 3

Step3:

LCM(3, 786) = 786

GCD(3, 786) = ( 3 x 786 ) / 786

= 3 / 786

= 3

So, Greatest Common Divisor of 642, 285, 177, 786 is 3
