Given numbers are 291,681,211,419,720

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

The LCM of 291,681,211,419,720 is 1401607995120.

Find LCM of 291,681,211,419,720 with Prime Factorization

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

3 x 97 x 227 x 211 x 419 x 240 = 1401607995120

Therefore, the lowest common multiple of 291,681,211,419,720 is 1401607995120.

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 681 x 211 x 419 x 720 = 12614471956080

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

681 : 1, 3, 227, 681

211 : 1, 211

419 : 1, 419

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,681,211,419,720, is 1.

Now, the common factors can be found like this.

291:3x 97

681:3x 227

211:211

419:419

720:2x 2x 2x 2x 3x 3x 5

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 12614471956080/(1x9)

LCM = 12614471956080/9

LCM = 1401607995120

Thus, we can understand that the LCM of 291,681,211,419,720 is 1401607995120.
