Given numbers are 409, 600, 220, 647

The list of prime factors of all numbers are

Prime factors of 409 are 409

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 647 are 647

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

Given numbers are 409, 600, 220, 647

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

Apply this formula for all numbers.

Step1:

LCM(409, 600) = 245400

GCD(409, 600) = ( 409 x 600 ) / 245400

= 409 / 600

= 409

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 409, 600, 220, 647 is 1
