Given numbers are 440, 561, 730, 427

The list of prime factors of all numbers are

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

Prime factors of 561 are 3 x 11 x 17

Prime factors of 730 are 2 x 5 x 73

Prime factors of 427 are 7 x 61

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

Given numbers are 440, 561, 730, 427

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

Apply this formula for all numbers.

Step1:

LCM(440, 561) = 22440

GCD(440, 561) = ( 440 x 561 ) / 22440

= 440 / 561

= 440

Step2:

LCM(11, 730) = 8030

GCD(11, 730) = ( 11 x 730 ) / 8030

= 11 / 730

= 11

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 440, 561, 730, 427 is 1
