Given numbers are 501, 247, 31, 780

The list of prime factors of all numbers are

Prime factors of 501 are 3 x 167

Prime factors of 247 are 13 x 19

Prime factors of 31 are 31

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 501, 247, 31, 780

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

Apply this formula for all numbers.

Step1:

LCM(501, 247) = 123747

GCD(501, 247) = ( 501 x 247 ) / 123747

= 501 / 247

= 501

Step2:

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

= 1 / 31

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 501, 247, 31, 780 is 1
