Given numbers are 987, 818, 770, 130

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 818 are 2 x 409

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 987, 818, 770, 130

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

Apply this formula for all numbers.

Step1:

LCM(987, 818) = 807366

GCD(987, 818) = ( 987 x 818 ) / 807366

= 987 / 818

= 987

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 987, 818, 770, 130 is 1
