Given numbers are 409,923,416,639

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

The LCM of 409,923,416,639 is 108722016.

Find LCM of 409,923,416,639 with Prime Factorization

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

13 x 71 x 409 x 1 x 32 x 9 = 108722016

Therefore, the lowest common multiple of 409,923,416,639 is 108722016.

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.

409 x 923 x 416 x 639 = 100350420768

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.

409 : 1, 409

923 : 1, 13, 71, 923

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,923,416,639, is 1.

Now, the common factors can be found like this.

409:409

923:13x 71

416:2x 2x 2x 2x 2x 13

639:3x 3x 71

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

13x 71 = 923

Therefore, the value for common factors is 923.

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 = 100350420768/(1x923)

LCM = 100350420768/923

LCM = 108722016

Thus, we can understand that the LCM of 409,923,416,639 is 108722016.
