Given numbers are 650, 870, 445, 421

The list of prime factors of all numbers are

Prime factors of 650 are 2 x 5 x 5 x 13

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

Prime factors of 445 are 5 x 89

Prime factors of 421 are 421

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

Given numbers are 650, 870, 445, 421

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

Apply this formula for all numbers.

Step1:

LCM(650, 870) = 56550

GCD(650, 870) = ( 650 x 870 ) / 56550

= 650 / 870

= 650

Step2:

LCM(10, 445) = 890

GCD(10, 445) = ( 10 x 445 ) / 890

= 10 / 445

= 10

Step3:

LCM(5, 421) = 2105

GCD(5, 421) = ( 5 x 421 ) / 2105

= 5 / 421

= 5

So, Greatest Common Divisor of 650, 870, 445, 421 is 1
