Given numbers are 215, 379, 540, 243

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 379 are 379

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

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 215, 379, 540, 243

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

Apply this formula for all numbers.

Step1:

LCM(215, 379) = 81485

GCD(215, 379) = ( 215 x 379 ) / 81485

= 215 / 379

= 215

Step2:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 215, 379, 540, 243 is 1
