Given numbers are 668,416,899,921

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

The LCM of 668,416,899,921 is 57521357088.

Find LCM of 668,416,899,921 with Prime Factorization

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

2 x 2 x 167 x 104 x 899 x 921 = 57521357088

Therefore, the lowest common multiple of 668,416,899,921 is 57521357088.

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.

668 x 416 x 899 x 921 = 230085428352

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.

668 : 1, 2, 4, 167, 334, 668

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

899 : 1, 29, 31, 899

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,416,899,921, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

416:2x 2x 2x 2x 2x 13

899:29x 31

921:3x 307

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 230085428352/(1x4)

LCM = 230085428352/4

LCM = 57521357088

Thus, we can understand that the LCM of 668,416,899,921 is 57521357088.
