Given numbers are 420, 606, 291, 470

The list of prime factors of all numbers are

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

Prime factors of 606 are 2 x 3 x 101

Prime factors of 291 are 3 x 97

Prime factors of 470 are 2 x 5 x 47

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

Given numbers are 420, 606, 291, 470

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

Apply this formula for all numbers.

Step1:

LCM(420, 606) = 42420

GCD(420, 606) = ( 420 x 606 ) / 42420

= 420 / 606

= 420

Step2:

LCM(6, 291) = 582

GCD(6, 291) = ( 6 x 291 ) / 582

= 6 / 291

= 6

Step3:

LCM(3, 470) = 1410

GCD(3, 470) = ( 3 x 470 ) / 1410

= 3 / 470

= 3

So, Greatest Common Divisor of 420, 606, 291, 470 is 1
