Given numbers are 291,989,301,430

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

The LCM of 291,989,301,430 is 20145930.

Find LCM of 291,989,301,430 with Prime Factorization

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

43 x 291 x 23 x 7 x 10 = 20145930

Therefore, the lowest common multiple of 291,989,301,430 is 20145930.

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.

291 x 989 x 301 x 430 = 37249824570

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.

291 : 1, 3, 97, 291

989 : 1, 23, 43, 989

301 : 1, 7, 43, 301

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,989,301,430, is 1.

Now, the common factors can be found like this.

291:3x 97

989:23x 43

301:7x 43

430:2x 5x 43

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

43x 43 = 1849

Therefore, the value for common factors is 1849.

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 = 37249824570/(1x1849)

LCM = 37249824570/1849

LCM = 20145930

Thus, we can understand that the LCM of 291,989,301,430 is 20145930.
