Given numbers are 407, 678, 245, 240

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 678 are 2 x 3 x 113

Prime factors of 245 are 5 x 7 x 7

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 407, 678, 245, 240

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

Apply this formula for all numbers.

Step1:

LCM(407, 678) = 275946

GCD(407, 678) = ( 407 x 678 ) / 275946

= 407 / 678

= 407

Step2:

LCM(1, 245) = 245

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

= 1 / 245

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 407, 678, 245, 240 is 1
