Given numbers are 245, 357, 553, 648

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 357 are 3 x 7 x 17

Prime factors of 553 are 7 x 79

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 245, 357, 553, 648

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

Apply this formula for all numbers.

Step1:

LCM(245, 357) = 12495

GCD(245, 357) = ( 245 x 357 ) / 12495

= 245 / 357

= 245

Step2:

LCM(7, 553) = 553

GCD(7, 553) = ( 7 x 553 ) / 553

= 7 / 553

= 7

Step3:

LCM(7, 648) = 4536

GCD(7, 648) = ( 7 x 648 ) / 4536

= 7 / 648

= 7

So, Greatest Common Divisor of 245, 357, 553, 648 is 1
