Given numbers are 418,780,806,435,945

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

The LCM of 418,780,806,435,945 is 9232963740.

Find LCM of 418,780,806,435,945 with Prime Factorization

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

2 x 3 x 5 x 13 x 209 x 2 x 31 x 29 x 63 = 9232963740

Therefore, the lowest common multiple of 418,780,806,435,945 is 9232963740.

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.

418 x 780 x 806 x 435 x 945 = 108025675758000

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

806 : 1, 2, 13, 26, 31, 62, 403, 806

435 : 1, 3, 5, 15, 29, 87, 145, 435

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,780,806,435,945, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

780:2x 2x 3x 5x 13

806:2x 13x 31

435:3x 5x 29

945:3x 3x 3x 5x 7

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

2x 2x 3x 3x 5x 5x 13 = 11700

Therefore, the value for common factors is 11700.

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 = 108025675758000/(1x11700)

LCM = 108025675758000/11700

LCM = 9232963740

Thus, we can understand that the LCM of 418,780,806,435,945 is 9232963740.
