Given numbers are 406, 642, 290, 407

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 642 are 2 x 3 x 107

Prime factors of 290 are 2 x 5 x 29

Prime factors of 407 are 11 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 406, 642, 290, 407

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

Apply this formula for all numbers.

Step1:

LCM(406, 642) = 130326

GCD(406, 642) = ( 406 x 642 ) / 130326

= 406 / 642

= 406

Step2:

LCM(2, 290) = 290

GCD(2, 290) = ( 2 x 290 ) / 290

= 2 / 290

= 2

Step3:

LCM(2, 407) = 814

GCD(2, 407) = ( 2 x 407 ) / 814

= 2 / 407

= 2

So, Greatest Common Divisor of 406, 642, 290, 407 is 1
