Given numbers are 791, 520, 278, 245

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

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

Prime factors of 278 are 2 x 139

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 791, 520, 278, 245

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

Apply this formula for all numbers.

Step1:

LCM(791, 520) = 411320

GCD(791, 520) = ( 791 x 520 ) / 411320

= 791 / 520

= 791

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 791, 520, 278, 245 is 1
