Given numbers are 660, 300, 220, 403

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

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

Prime factors of 403 are 13 x 31

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

Given numbers are 660, 300, 220, 403

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

Apply this formula for all numbers.

Step1:

LCM(660, 300) = 3300

GCD(660, 300) = ( 660 x 300 ) / 3300

= 660 / 300

= 660

Step2:

LCM(60, 220) = 660

GCD(60, 220) = ( 60 x 220 ) / 660

= 60 / 220

= 60

Step3:

LCM(20, 403) = 8060

GCD(20, 403) = ( 20 x 403 ) / 8060

= 20 / 403

= 20

So, Greatest Common Divisor of 660, 300, 220, 403 is 1
