Given numbers are 665, 488, 616, 400

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 488 are 2 x 2 x 2 x 61

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

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

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

Given numbers are 665, 488, 616, 400

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

Apply this formula for all numbers.

Step1:

LCM(665, 488) = 324520

GCD(665, 488) = ( 665 x 488 ) / 324520

= 665 / 488

= 665

Step2:

LCM(1, 616) = 616

GCD(1, 616) = ( 1 x 616 ) / 616

= 1 / 616

= 1

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 665, 488, 616, 400 is 1
