Given numbers are 245, 630, 720, 206

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 206 are 2 x 103

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

Given numbers are 245, 630, 720, 206

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

Apply this formula for all numbers.

Step1:

LCM(245, 630) = 4410

GCD(245, 630) = ( 245 x 630 ) / 4410

= 245 / 630

= 245

Step2:

LCM(35, 720) = 5040

GCD(35, 720) = ( 35 x 720 ) / 5040

= 35 / 720

= 35

Step3:

LCM(5, 206) = 1030

GCD(5, 206) = ( 5 x 206 ) / 1030

= 5 / 206

= 5

So, Greatest Common Divisor of 245, 630, 720, 206 is 1
