Given numbers are 618, 211, 420, 900

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 211 are 211

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

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

Given numbers are 618, 211, 420, 900

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

Apply this formula for all numbers.

Step1:

LCM(618, 211) = 130398

GCD(618, 211) = ( 618 x 211 ) / 130398

= 618 / 211

= 618

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

= 1 / 900

= 1

So, Greatest Common Divisor of 618, 211, 420, 900 is 1
