Given numbers are 1,223,286,715

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

The LCM of 1,223,286,715 is 318890.

Find LCM of 1,223,286,715 with Prime Factorization

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

11 x 13 x 1 x 223 x 2 x 5 = 318890

Therefore, the lowest common multiple of 1,223,286,715 is 318890.

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.

1 x 223 x 286 x 715 = 45601270

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.

1 : 1

223 : 1, 223

286 : 1, 2, 11, 13, 22, 26, 143, 286

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,223,286,715, is 1.

Now, the common factors can be found like this.

1:

223:223

286:2x 11x 13

715:5x 11x 13

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 45601270/(1x143)

LCM = 45601270/143

LCM = 318890

Thus, we can understand that the LCM of 1,223,286,715 is 318890.
