Given numbers are 378,797,936,645

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

The LCM of 378,797,936,645 is 3368153880.

Find LCM of 378,797,936,645 with Prime Factorization

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

2 x 3 x 3 x 21 x 797 x 52 x 215 = 3368153880

Therefore, the lowest common multiple of 378,797,936,645 is 3368153880.

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.

378 x 797 x 936 x 645 = 181880309520

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.

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

797 : 1, 797

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,797,936,645, is 1.

Now, the common factors can be found like this.

378:2x 3x 3x 3x 7

797:797

936:2x 2x 2x 3x 3x 13

645:3x 5x 43

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

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 181880309520/(1x54)

LCM = 181880309520/54

LCM = 3368153880

Thus, we can understand that the LCM of 378,797,936,645 is 3368153880.
