Given numbers are 847, 751, 75, 420

The list of prime factors of all numbers are

Prime factors of 847 are 7 x 11 x 11

Prime factors of 751 are 751

Prime factors of 75 are 3 x 5 x 5

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

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

Given numbers are 847, 751, 75, 420

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

Apply this formula for all numbers.

Step1:

LCM(847, 751) = 636097

GCD(847, 751) = ( 847 x 751 ) / 636097

= 847 / 751

= 847

Step2:

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

= 1 / 75

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 847, 751, 75, 420 is 1
