Given numbers are 987, 505, 200, 830

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 505 are 5 x 101

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 987, 505, 200, 830

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

Apply this formula for all numbers.

Step1:

LCM(987, 505) = 498435

GCD(987, 505) = ( 987 x 505 ) / 498435

= 987 / 505

= 987

Step2:

LCM(1, 200) = 200

GCD(1, 200) = ( 1 x 200 ) / 200

= 1 / 200

= 1

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 987, 505, 200, 830 is 1
