Given numbers are 474,399,921,691

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

The LCM of 474,399,921,691 is 13373540754.

Find LCM of 474,399,921,691 with Prime Factorization

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

3 x 158 x 133 x 307 x 691 = 13373540754

Therefore, the lowest common multiple of 474,399,921,691 is 13373540754.

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.

474 x 399 x 921 x 691 = 120361866786

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.

474 : 1, 2, 3, 6, 79, 158, 237, 474

399 : 1, 3, 7, 19, 21, 57, 133, 399

921 : 1, 3, 307, 921

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,399,921,691, is 1.

Now, the common factors can be found like this.

474:2x 3x 79

399:3x 7x 19

921:3x 307

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.

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 = 120361866786/(1x9)

LCM = 120361866786/9

LCM = 13373540754

Thus, we can understand that the LCM of 474,399,921,691 is 13373540754.
