Given numbers are 220, 840, 728, 203

The list of prime factors of all numbers are

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

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 203 are 7 x 29

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

Given numbers are 220, 840, 728, 203

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

Apply this formula for all numbers.

Step1:

LCM(220, 840) = 9240

GCD(220, 840) = ( 220 x 840 ) / 9240

= 220 / 840

= 220

Step2:

LCM(20, 728) = 3640

GCD(20, 728) = ( 20 x 728 ) / 3640

= 20 / 728

= 20

Step3:

LCM(4, 203) = 812

GCD(4, 203) = ( 4 x 203 ) / 812

= 4 / 203

= 4

So, Greatest Common Divisor of 220, 840, 728, 203 is 1
