Given numbers are 245, 505, 831, 506

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 505 are 5 x 101

Prime factors of 831 are 3 x 277

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 245, 505, 831, 506

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

Apply this formula for all numbers.

Step1:

LCM(245, 505) = 24745

GCD(245, 505) = ( 245 x 505 ) / 24745

= 245 / 505

= 245

Step2:

LCM(5, 831) = 4155

GCD(5, 831) = ( 5 x 831 ) / 4155

= 5 / 831

= 5

Step3:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

So, Greatest Common Divisor of 245, 505, 831, 506 is 1
