Given numbers are 391,391,101,506

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

The LCM of 391,391,101,506 is 868802.

Find LCM of 391,391,101,506 with Prime Factorization

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

17 x 23 x 1 x 1 x 101 x 22 = 868802

Therefore, the lowest common multiple of 391,391,101,506 is 868802.

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.

391 x 391 x 101 x 506 = 7813136386

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.

391 : 1, 17, 23, 391

391 : 1, 17, 23, 391

101 : 1, 101

506 : 1, 2, 11, 22, 23, 46, 253, 506

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,391,101,506, is 1.

Now, the common factors can be found like this.

391:17x 23

391:17x 23

101:101

506:2x 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.

17x 23x 23 = 8993

Therefore, the value for common factors is 8993.

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 = 7813136386/(1x8993)

LCM = 7813136386/8993

LCM = 868802

Thus, we can understand that the LCM of 391,391,101,506 is 868802.
