Given numbers are 197, 413, 550, 640

The list of prime factors of all numbers are

Prime factors of 197 are 197

Prime factors of 413 are 7 x 59

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 197, 413, 550, 640

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

Apply this formula for all numbers.

Step1:

LCM(197, 413) = 81361

GCD(197, 413) = ( 197 x 413 ) / 81361

= 197 / 413

= 197

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 197, 413, 550, 640 is 1
