Given numbers are 520, 280, 987, 247

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 987 are 3 x 7 x 47

Prime factors of 247 are 13 x 19

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

Given numbers are 520, 280, 987, 247

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

Apply this formula for all numbers.

Step1:

LCM(520, 280) = 3640

GCD(520, 280) = ( 520 x 280 ) / 3640

= 520 / 280

= 520

Step2:

LCM(40, 987) = 39480

GCD(40, 987) = ( 40 x 987 ) / 39480

= 40 / 987

= 40

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 520, 280, 987, 247 is 1
