Given numbers are 979,398,890,423

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

The LCM of 979,398,890,423 is 824092830.

Find LCM of 979,398,890,423 with Prime Factorization

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

2 x 89 x 11 x 199 x 5 x 423 = 824092830

Therefore, the lowest common multiple of 979,398,890,423 is 824092830.

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.

979 x 398 x 890 x 423 = 146688523740

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.

979 : 1, 11, 89, 979

398 : 1, 2, 199, 398

890 : 1, 2, 5, 10, 89, 178, 445, 890

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,398,890,423, is 1.

Now, the common factors can be found like this.

979:11x 89

398:2x 199

890:2x 5x 89

423:3x 3x 47

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

2x 89 = 178

Therefore, the value for common factors is 178.

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 = 146688523740/(1x178)

LCM = 146688523740/178

LCM = 824092830

Thus, we can understand that the LCM of 979,398,890,423 is 824092830.
