Given numbers are 621, 170, 64, 486

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 170 are 2 x 5 x 17

Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 621, 170, 64, 486

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

Apply this formula for all numbers.

Step1:

LCM(621, 170) = 105570

GCD(621, 170) = ( 621 x 170 ) / 105570

= 621 / 170

= 621

Step2:

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

= 1 / 64

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 621, 170, 64, 486 is 1
