Given numbers are 245, 658, 510, 905

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 658 are 2 x 7 x 47

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 905 are 5 x 181

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

Given numbers are 245, 658, 510, 905

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

Apply this formula for all numbers.

Step1:

LCM(245, 658) = 23030

GCD(245, 658) = ( 245 x 658 ) / 23030

= 245 / 658

= 245

Step2:

LCM(7, 510) = 3570

GCD(7, 510) = ( 7 x 510 ) / 3570

= 7 / 510

= 7

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 245, 658, 510, 905 is 1
