Given numbers are 243, 441, 148, 550

The list of prime factors of all numbers are

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

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 148 are 2 x 2 x 37

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 243, 441, 148, 550

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

Apply this formula for all numbers.

Step1:

LCM(243, 441) = 11907

GCD(243, 441) = ( 243 x 441 ) / 11907

= 243 / 441

= 243

Step2:

LCM(9, 148) = 1332

GCD(9, 148) = ( 9 x 148 ) / 1332

= 9 / 148

= 9

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 243, 441, 148, 550 is 1
