Given numbers are 642, 366, 418, 655

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

Apply this formula for all numbers.

Step1:

LCM(642, 366) = 39162

GCD(642, 366) = ( 642 x 366 ) / 39162

= 642 / 366

= 642

Step2:

LCM(6, 418) = 1254

GCD(6, 418) = ( 6 x 418 ) / 1254

= 6 / 418

= 6

Step3:

LCM(2, 655) = 1310

GCD(2, 655) = ( 2 x 655 ) / 1310

= 2 / 655

= 2

So, Greatest Common Divisor of 642, 366, 418, 655 is 1
