Given numbers are 413,286,247,620

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

The LCM of 413,286,247,620 is 695715020.

Find LCM of 413,286,247,620 with Prime Factorization

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

2 x 13 x 413 x 11 x 19 x 310 = 695715020

Therefore, the lowest common multiple of 413,286,247,620 is 695715020.

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.

413 x 286 x 247 x 620 = 18088590520

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.

413 : 1, 7, 59, 413

286 : 1, 2, 11, 13, 22, 26, 143, 286

247 : 1, 13, 19, 247

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 413,286,247,620, is 1.

Now, the common factors can be found like this.

413:7x 59

286:2x 11x 13

247:13x 19

620:2x 2x 5x 31

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 18088590520/(1x26)

LCM = 18088590520/26

LCM = 695715020

Thus, we can understand that the LCM of 413,286,247,620 is 695715020.
