Given numbers are 476, 455, 840, 790

The list of prime factors of all numbers are

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 455 are 5 x 7 x 13

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

Prime factors of 790 are 2 x 5 x 79

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

Given numbers are 476, 455, 840, 790

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

Apply this formula for all numbers.

Step1:

LCM(476, 455) = 30940

GCD(476, 455) = ( 476 x 455 ) / 30940

= 476 / 455

= 476

Step2:

LCM(7, 840) = 840

GCD(7, 840) = ( 7 x 840 ) / 840

= 7 / 840

= 7

Step3:

LCM(7, 790) = 5530

GCD(7, 790) = ( 7 x 790 ) / 5530

= 7 / 790

= 7

So, Greatest Common Divisor of 476, 455, 840, 790 is 1
