Given numbers are 578, 320, 668, 783

The list of prime factors of all numbers are

Prime factors of 578 are 2 x 17 x 17

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

Prime factors of 668 are 2 x 2 x 167

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 578, 320, 668, 783

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

Apply this formula for all numbers.

Step1:

LCM(578, 320) = 92480

GCD(578, 320) = ( 578 x 320 ) / 92480

= 578 / 320

= 578

Step2:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

Step3:

LCM(2, 783) = 1566

GCD(2, 783) = ( 2 x 783 ) / 1566

= 2 / 783

= 2

So, Greatest Common Divisor of 578, 320, 668, 783 is 1
