Given numbers are 310,154,253,687

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

The LCM of 310,154,253,687 is 377169870.

Find LCM of 310,154,253,687 with Prime Factorization

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

2 x 11 x 155 x 7 x 23 x 687 = 377169870

Therefore, the lowest common multiple of 310,154,253,687 is 377169870.

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.

310 x 154 x 253 x 687 = 8297737140

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.

310 : 1, 2, 5, 10, 31, 62, 155, 310

154 : 1, 2, 7, 11, 14, 22, 77, 154

253 : 1, 11, 23, 253

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,154,253,687, is 1.

Now, the common factors can be found like this.

310:2x 5x 31

154:2x 7x 11

253:11x 23

687:3x 229

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 8297737140/(1x22)

LCM = 8297737140/22

LCM = 377169870

Thus, we can understand that the LCM of 310,154,253,687 is 377169870.
