Given numbers are 870, 820, 521, 217

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 521 are 521

Prime factors of 217 are 7 x 31

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

Given numbers are 870, 820, 521, 217

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, 521) = 5210

GCD(10, 521) = ( 10 x 521 ) / 5210

= 10 / 521

= 10

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 870, 820, 521, 217 is 1
