Given numbers are 197, 140, 704, 648

The list of prime factors of all numbers are

Prime factors of 197 are 197

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 704 are 2 x 2 x 2 x 2 x 2 x 2 x 11

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 197, 140, 704, 648

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

Apply this formula for all numbers.

Step1:

LCM(197, 140) = 27580

GCD(197, 140) = ( 197 x 140 ) / 27580

= 197 / 140

= 197

Step2:

LCM(1, 704) = 704

GCD(1, 704) = ( 1 x 704 ) / 704

= 1 / 704

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 197, 140, 704, 648 is 1
