Given numbers are 870, 820, 995, 471

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 995 are 5 x 199

Prime factors of 471 are 3 x 157

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

Given numbers are 870, 820, 995, 471

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

Apply this formula for all numbers.

Step1:

LCM(870, 820) = 71340

GCD(870, 820) = ( 870 x 820 ) / 71340

= 870 / 820

= 870

Step2:

LCM(10, 995) = 1990

GCD(10, 995) = ( 10 x 995 ) / 1990

= 10 / 995

= 10

Step3:

LCM(5, 471) = 2355

GCD(5, 471) = ( 5 x 471 ) / 2355

= 5 / 471

= 5

So, Greatest Common Divisor of 870, 820, 995, 471 is 1
