Given numbers are 642, 275, 814, 306

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 275 are 5 x 5 x 11

Prime factors of 814 are 2 x 11 x 37

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 642, 275, 814, 306

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

Apply this formula for all numbers.

Step1:

LCM(642, 275) = 176550

GCD(642, 275) = ( 642 x 275 ) / 176550

= 642 / 275

= 642

Step2:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 642, 275, 814, 306 is 1
