Given numbers are 544, 815, 641, 400

The list of prime factors of all numbers are

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 815 are 5 x 163

Prime factors of 641 are 641

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 544, 815, 641, 400

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

Apply this formula for all numbers.

Step1:

LCM(544, 815) = 443360

GCD(544, 815) = ( 544 x 815 ) / 443360

= 544 / 815

= 544

Step2:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

Step3:

LCM(1, 400) = 400

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

= 1 / 400

= 1

So, Greatest Common Divisor of 544, 815, 641, 400 is 1
