Given numbers are 667,281,620,785

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

The LCM of 667,281,620,785 is 18244144180.

Find LCM of 667,281,620,785 with Prime Factorization

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

5 x 667 x 281 x 124 x 157 = 18244144180

Therefore, the lowest common multiple of 667,281,620,785 is 18244144180.

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.

667 x 281 x 620 x 785 = 91220720900

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.

667 : 1, 23, 29, 667

281 : 1, 281

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,281,620,785, is 1.

Now, the common factors can be found like this.

667:23x 29

281:281

620:2x 2x 5x 31

785:5x 157

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

5 = 5

Therefore, the value for common factors is 5.

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 = 91220720900/(1x5)

LCM = 91220720900/5

LCM = 18244144180

Thus, we can understand that the LCM of 667,281,620,785 is 18244144180.
