Given numbers are 425, 148, 245, 660

The list of prime factors of all numbers are

Prime factors of 425 are 5 x 5 x 17

Prime factors of 148 are 2 x 2 x 37

Prime factors of 245 are 5 x 7 x 7

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 425, 148, 245, 660

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

Apply this formula for all numbers.

Step1:

LCM(425, 148) = 62900

GCD(425, 148) = ( 425 x 148 ) / 62900

= 425 / 148

= 425

Step2:

LCM(1, 245) = 245

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

= 1 / 245

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 425, 148, 245, 660 is 1
