Given numbers are 816, 978, 965, 987

The list of prime factors of all numbers are

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

Prime factors of 978 are 2 x 3 x 163

Prime factors of 965 are 5 x 193

Prime factors of 987 are 3 x 7 x 47

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

Given numbers are 816, 978, 965, 987

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

Apply this formula for all numbers.

Step1:

LCM(816, 978) = 133008

GCD(816, 978) = ( 816 x 978 ) / 133008

= 816 / 978

= 816

Step2:

LCM(6, 965) = 5790

GCD(6, 965) = ( 6 x 965 ) / 5790

= 6 / 965

= 6

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 816, 978, 965, 987 is 1
