Given numbers are 406, 492, 352, 643

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 643 are 643

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

Given numbers are 406, 492, 352, 643

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

Apply this formula for all numbers.

Step1:

LCM(406, 492) = 99876

GCD(406, 492) = ( 406 x 492 ) / 99876

= 406 / 492

= 406

Step2:

LCM(2, 352) = 352

GCD(2, 352) = ( 2 x 352 ) / 352

= 2 / 352

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 406, 492, 352, 643 is 1
