Given numbers are 243, 145, 780, 149

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 145 are 5 x 29

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 149 are 149

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

Given numbers are 243, 145, 780, 149

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

Apply this formula for all numbers.

Step1:

LCM(243, 145) = 35235

GCD(243, 145) = ( 243 x 145 ) / 35235

= 243 / 145

= 243

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 149) = 149

GCD(1, 149) = ( 1 x 149 ) / 149

= 1 / 149

= 1

So, Greatest Common Divisor of 243, 145, 780, 149 is 1
