Given numbers are 287,991,135,164

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

The LCM of 287,991,135,164 is 153585180.

Find LCM of 287,991,135,164 with Prime Factorization

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

41 x 7 x 991 x 135 x 4 = 153585180

Therefore, the lowest common multiple of 287,991,135,164 is 153585180.

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.

287 x 991 x 135 x 164 = 6296992380

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.

287 : 1, 7, 41, 287

991 : 1, 991

135 : 1, 3, 5, 9, 15, 27, 45, 135

164 : 1, 2, 4, 41, 82, 164

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,991,135,164, is 1.

Now, the common factors can be found like this.

287:7x 41

991:991

135:3x 3x 3x 5

164:2x 2x 41

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

41 = 41

Therefore, the value for common factors is 41.

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 = 6296992380/(1x41)

LCM = 6296992380/41

LCM = 153585180

Thus, we can understand that the LCM of 287,991,135,164 is 153585180.
