Given numbers are 642, 758, 427

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

Apply this formula for all numbers.

Step1:

LCM(642, 758) = 243318

GCD(642, 758) = ( 642 x 758 ) / 243318

= 642 / 758

= 642

Step2:

LCM(2, 427) = 854

GCD(2, 427) = ( 2 x 427 ) / 854

= 2 / 427

= 2

So, Greatest Common Divisor of 642, 758, 427 is 1
