Given numbers are 221, 730, 245, 358

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 730 are 2 x 5 x 73

Prime factors of 245 are 5 x 7 x 7

Prime factors of 358 are 2 x 179

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

Given numbers are 221, 730, 245, 358

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

Apply this formula for all numbers.

Step1:

LCM(221, 730) = 161330

GCD(221, 730) = ( 221 x 730 ) / 161330

= 221 / 730

= 221

Step2:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

Step3:

LCM(1, 358) = 358

GCD(1, 358) = ( 1 x 358 ) / 358

= 1 / 358

= 1

So, Greatest Common Divisor of 221, 730, 245, 358 is 1
