Given numbers are 961, 648, 245, 564

The list of prime factors of all numbers are

Prime factors of 961 are 31 x 31

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

Prime factors of 245 are 5 x 7 x 7

Prime factors of 564 are 2 x 2 x 3 x 47

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

Given numbers are 961, 648, 245, 564

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

Apply this formula for all numbers.

Step1:

LCM(961, 648) = 622728

GCD(961, 648) = ( 961 x 648 ) / 622728

= 961 / 648

= 961

Step2:

LCM(1, 245) = 245

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

= 1 / 245

= 1

Step3:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

So, Greatest Common Divisor of 961, 648, 245, 564 is 1
