Given numbers are 243, 240, 747, 151

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 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 747 are 3 x 3 x 83

Prime factors of 151 are 151

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

Given numbers are 243, 240, 747, 151

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

Apply this formula for all numbers.

Step1:

LCM(243, 240) = 19440

GCD(243, 240) = ( 243 x 240 ) / 19440

= 243 / 240

= 243

Step2:

LCM(3, 747) = 747

GCD(3, 747) = ( 3 x 747 ) / 747

= 3 / 747

= 3

Step3:

LCM(3, 151) = 453

GCD(3, 151) = ( 3 x 151 ) / 453

= 3 / 151

= 3

So, Greatest Common Divisor of 243, 240, 747, 151 is 1
