Given numbers are 243, 770, 551, 124

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 770 are 2 x 5 x 7 x 11

Prime factors of 551 are 19 x 29

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 243, 770, 551, 124

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

Apply this formula for all numbers.

Step1:

LCM(243, 770) = 187110

GCD(243, 770) = ( 243 x 770 ) / 187110

= 243 / 770

= 243

Step2:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 243, 770, 551, 124 is 1
