Given numbers are 644, 300, 412, 243

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 412 are 2 x 2 x 103

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 644, 300, 412, 243

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

Apply this formula for all numbers.

Step1:

LCM(644, 300) = 48300

GCD(644, 300) = ( 644 x 300 ) / 48300

= 644 / 300

= 644

Step2:

LCM(4, 412) = 412

GCD(4, 412) = ( 4 x 412 ) / 412

= 4 / 412

= 4

Step3:

LCM(4, 243) = 972

GCD(4, 243) = ( 4 x 243 ) / 972

= 4 / 243

= 4

So, Greatest Common Divisor of 644, 300, 412, 243 is 1
