Given numbers are 243,409,715,409

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 243,409,715,409 is 71061705.

Find LCM of 243,409,715,409 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

409 x 243 x 1 x 715 x 1 = 71061705

Therefore, the lowest common multiple of 243,409,715,409 is 71061705.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

243 x 409 x 715 x 409 = 29064237345

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

243 : 1, 3, 9, 27, 81, 243

409 : 1, 409

715 : 1, 5, 11, 13, 55, 65, 143, 715

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,409,715,409, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

409:409

715:5x 11x 13

409:409

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

409 = 409

Therefore, the value for common factors is 409.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 29064237345/(1x409)

LCM = 29064237345/409

LCM = 71061705

Thus, we can understand that the LCM of 243,409,715,409 is 71061705.
