Given numbers are 245, 520, 807, 407

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

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

Prime factors of 807 are 3 x 269

Prime factors of 407 are 11 x 37

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

Given numbers are 245, 520, 807, 407

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

Apply this formula for all numbers.

Step1:

LCM(245, 520) = 25480

GCD(245, 520) = ( 245 x 520 ) / 25480

= 245 / 520

= 245

Step2:

LCM(5, 807) = 4035

GCD(5, 807) = ( 5 x 807 ) / 4035

= 5 / 807

= 5

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 245, 520, 807, 407 is 1
