Given numbers are 642, 340, 241, 609

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

Apply this formula for all numbers.

Step1:

LCM(642, 340) = 109140

GCD(642, 340) = ( 642 x 340 ) / 109140

= 642 / 340

= 642

Step2:

LCM(2, 241) = 482

GCD(2, 241) = ( 2 x 241 ) / 482

= 2 / 241

= 2

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 642, 340, 241, 609 is 1
