Given numbers are 430, 503, 561, 986

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 503 are 503

Prime factors of 561 are 3 x 11 x 17

Prime factors of 986 are 2 x 17 x 29

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

Given numbers are 430, 503, 561, 986

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

Apply this formula for all numbers.

Step1:

LCM(430, 503) = 216290

GCD(430, 503) = ( 430 x 503 ) / 216290

= 430 / 503

= 430

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 986) = 986

GCD(1, 986) = ( 1 x 986 ) / 986

= 1 / 986

= 1

So, Greatest Common Divisor of 430, 503, 561, 986 is 1
