Given numbers are 687,130,253,253

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

The LCM of 687,130,253,253 is 22595430.

Find LCM of 687,130,253,253 with Prime Factorization

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

11 x 23 x 687 x 130 x 1 x 1 = 22595430

Therefore, the lowest common multiple of 687,130,253,253 is 22595430.

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.

687 x 130 x 253 x 253 = 5716643790

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.

687 : 1, 3, 229, 687

130 : 1, 2, 5, 10, 13, 26, 65, 130

253 : 1, 11, 23, 253

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,130,253,253, is 1.

Now, the common factors can be found like this.

687:3x 229

130:2x 5x 13

253:11x 23

253:11x 23

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

11x 23 = 253

Therefore, the value for common factors is 253.

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 = 5716643790/(1x253)

LCM = 5716643790/253

LCM = 22595430

Thus, we can understand that the LCM of 687,130,253,253 is 22595430.
