Given numbers are 393,248,306,691

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

The LCM of 393,248,306,691 is 3434728824.

Find LCM of 393,248,306,691 with Prime Factorization

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

2 x 3 x 131 x 124 x 51 x 691 = 3434728824

Therefore, the lowest common multiple of 393,248,306,691 is 3434728824.

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.

393 x 248 x 306 x 691 = 20608372944

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.

393 : 1, 3, 131, 393

248 : 1, 2, 4, 8, 31, 62, 124, 248

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,248,306,691, is 1.

Now, the common factors can be found like this.

393:3x 131

248:2x 2x 2x 31

306:2x 3x 3x 17

691:691

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 = 20608372944/(1x6)

LCM = 20608372944/6

LCM = 3434728824

Thus, we can understand that the LCM of 393,248,306,691 is 3434728824.
