Given numbers are 662,163,161,920

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

The LCM of 662,163,161,920 is 347457320.

Find LCM of 662,163,161,920 with Prime Factorization

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

2 x 23 x 331 x 163 x 7 x 20 = 347457320

Therefore, the lowest common multiple of 662,163,161,920 is 347457320.

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.

662 x 163 x 161 x 920 = 15983036720

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.

662 : 1, 2, 331, 662

163 : 1, 163

161 : 1, 7, 23, 161

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,163,161,920, is 1.

Now, the common factors can be found like this.

662:2x 331

163:163

161:7x 23

920:2x 2x 2x 5x 23

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 15983036720/(1x46)

LCM = 15983036720/46

LCM = 347457320

Thus, we can understand that the LCM of 662,163,161,920 is 347457320.

Here are some samples of LCM of two or more Numbers calculations.
