Given numbers are 420, 833, 815, 907

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 833 are 7 x 7 x 17

Prime factors of 815 are 5 x 163

Prime factors of 907 are 907

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

Given numbers are 420, 833, 815, 907

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

Apply this formula for all numbers.

Step1:

LCM(420, 833) = 49980

GCD(420, 833) = ( 420 x 833 ) / 49980

= 420 / 833

= 420

Step2:

LCM(7, 815) = 5705

GCD(7, 815) = ( 7 x 815 ) / 5705

= 7 / 815

= 7

Step3:

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

= 1 / 907

= 1

So, Greatest Common Divisor of 420, 833, 815, 907 is 1
