Given numbers are 623, 455, 240, 440

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 455 are 5 x 7 x 13

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

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 623, 455, 240, 440

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

Apply this formula for all numbers.

Step1:

LCM(623, 455) = 40495

GCD(623, 455) = ( 623 x 455 ) / 40495

= 623 / 455

= 623

Step2:

LCM(7, 240) = 1680

GCD(7, 240) = ( 7 x 240 ) / 1680

= 7 / 240

= 7

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 623, 455, 240, 440 is 1
