Given numbers are 840, 495, 605, 407

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 605 are 5 x 11 x 11

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 840, 495, 605, 407

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

Apply this formula for all numbers.

Step1:

LCM(840, 495) = 27720

GCD(840, 495) = ( 840 x 495 ) / 27720

= 840 / 495

= 840

Step2:

LCM(15, 605) = 1815

GCD(15, 605) = ( 15 x 605 ) / 1815

= 15 / 605

= 15

Step3:

LCM(5, 407) = 2035

GCD(5, 407) = ( 5 x 407 ) / 2035

= 5 / 407

= 5

So, Greatest Common Divisor of 840, 495, 605, 407 is 1
