Given numbers are 642, 333, 777, 742

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

Apply this formula for all numbers.

Step1:

LCM(642, 333) = 71262

GCD(642, 333) = ( 642 x 333 ) / 71262

= 642 / 333

= 642

Step2:

LCM(3, 777) = 777

GCD(3, 777) = ( 3 x 777 ) / 777

= 3 / 777

= 3

Step3:

LCM(3, 742) = 2226

GCD(3, 742) = ( 3 x 742 ) / 2226

= 3 / 742

= 3

So, Greatest Common Divisor of 642, 333, 777, 742 is 1
