Given numbers are 291,422,993,578

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

The LCM of 291,422,993,578 is 11747116518.

Find LCM of 291,422,993,578 with Prime Factorization

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

2 x 3 x 97 x 211 x 331 x 289 = 11747116518

Therefore, the lowest common multiple of 291,422,993,578 is 11747116518.

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.

291 x 422 x 993 x 578 = 70482699108

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.

291 : 1, 3, 97, 291

422 : 1, 2, 211, 422

993 : 1, 3, 331, 993

578 : 1, 2, 17, 34, 289, 578

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,422,993,578, is 1.

Now, the common factors can be found like this.

291:3x 97

422:2x 211

993:3x 331

578:2x 17x 17

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 70482699108/(1x6)

LCM = 70482699108/6

LCM = 11747116518

Thus, we can understand that the LCM of 291,422,993,578 is 11747116518.
