Given numbers are 642, 864, 787, 339

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

Apply this formula for all numbers.

Step1:

LCM(642, 864) = 92448

GCD(642, 864) = ( 642 x 864 ) / 92448

= 642 / 864

= 642

Step2:

LCM(6, 787) = 4722

GCD(6, 787) = ( 6 x 787 ) / 4722

= 6 / 787

= 6

Step3:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

So, Greatest Common Divisor of 642, 864, 787, 339 is 1
