Given numbers are 513, 441, 355, 646

The list of prime factors of all numbers are

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 355 are 5 x 71

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 513, 441, 355, 646

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

Apply this formula for all numbers.

Step1:

LCM(513, 441) = 25137

GCD(513, 441) = ( 513 x 441 ) / 25137

= 513 / 441

= 513

Step2:

LCM(9, 355) = 3195

GCD(9, 355) = ( 9 x 355 ) / 3195

= 9 / 355

= 9

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 513, 441, 355, 646 is 1
