Given numbers are 220, 494, 71, 320

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 494 are 2 x 13 x 19

Prime factors of 71 are 71

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 220, 494, 71, 320

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

Apply this formula for all numbers.

Step1:

LCM(220, 494) = 54340

GCD(220, 494) = ( 220 x 494 ) / 54340

= 220 / 494

= 220

Step2:

LCM(2, 71) = 142

GCD(2, 71) = ( 2 x 71 ) / 142

= 2 / 71

= 2

Step3:

LCM(1, 320) = 320

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

= 1 / 320

= 1

So, Greatest Common Divisor of 220, 494, 71, 320 is 1
