Given numbers are 989, 210, 709, 816

The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 709 are 709

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 989, 210, 709, 816

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

Apply this formula for all numbers.

Step1:

LCM(989, 210) = 207690

GCD(989, 210) = ( 989 x 210 ) / 207690

= 989 / 210

= 989

Step2:

LCM(1, 709) = 709

GCD(1, 709) = ( 1 x 709 ) / 709

= 1 / 709

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 989, 210, 709, 816 is 1
