Given numbers are 643,662,378,924

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

The LCM of 643,662,378,924 is 1769919228.

Find LCM of 643,662,378,924 with Prime Factorization

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

2 x 3 x 7 x 643 x 331 x 9 x 22 = 1769919228

Therefore, the lowest common multiple of 643,662,378,924 is 1769919228.

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.

643 x 662 x 378 x 924 = 148673215152

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.

643 : 1, 643

662 : 1, 2, 331, 662

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,662,378,924, is 1.

Now, the common factors can be found like this.

643:643

662:2x 331

378:2x 3x 3x 3x 7

924:2x 2x 3x 7x 11

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 7 = 84

Therefore, the value for common factors is 84.

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 = 148673215152/(1x84)

LCM = 148673215152/84

LCM = 1769919228

Thus, we can understand that the LCM of 643,662,378,924 is 1769919228.
