Given numbers are 245, 542, 304, 220

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 542 are 2 x 271

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

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

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

Given numbers are 245, 542, 304, 220

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

Apply this formula for all numbers.

Step1:

LCM(245, 542) = 132790

GCD(245, 542) = ( 245 x 542 ) / 132790

= 245 / 542

= 245

Step2:

LCM(1, 304) = 304

GCD(1, 304) = ( 1 x 304 ) / 304

= 1 / 304

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 245, 542, 304, 220 is 1
