Given numbers are 654, 858, 487, 320

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 487 are 487

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 654, 858, 487, 320

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

Apply this formula for all numbers.

Step1:

LCM(654, 858) = 93522

GCD(654, 858) = ( 654 x 858 ) / 93522

= 654 / 858

= 654

Step2:

LCM(6, 487) = 2922

GCD(6, 487) = ( 6 x 487 ) / 2922

= 6 / 487

= 6

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 654, 858, 487, 320 is 1
