Given numbers are 660, 869, 400, 578

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 869 are 11 x 79

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 660, 869, 400, 578

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

Apply this formula for all numbers.

Step1:

LCM(660, 869) = 52140

GCD(660, 869) = ( 660 x 869 ) / 52140

= 660 / 869

= 660

Step2:

LCM(11, 400) = 4400

GCD(11, 400) = ( 11 x 400 ) / 4400

= 11 / 400

= 11

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 660, 869, 400, 578 is 1
