Given numbers are 158,676,910,780

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

The LCM of 158,676,910,780 is 5607420.

Find LCM of 158,676,910,780 with Prime Factorization

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

2 x 2 x 5 x 13 x 79 x 13 x 7 x 3 = 5607420

Therefore, the lowest common multiple of 158,676,910,780 is 5607420.

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.

158 x 676 x 910 x 780 = 75812318400

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.

158 : 1, 2, 79, 158

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,676,910,780, is 2.

Now, the common factors can be found like this.

158:2x 79

676:2x 2x 13x 13

910:2x 5x 7x 13

780:2x 2x 3x 5x 13

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 2x 5x 13x 13 = 6760

Therefore, the value for common factors is 6760.

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 = 75812318400/(2x6760)

LCM = 75812318400/13520

LCM = 5607420

Thus, we can understand that the LCM of 158,676,910,780 is 5607420.
