Given numbers are 977,344,240,490,398

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

The LCM of 977,344,240,490,398 is 98315822640.

Find LCM of 977,344,240,490,398 with Prime Factorization

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

2 x 2 x 2 x 5 x 977 x 43 x 6 x 49 x 199 = 98315822640

Therefore, the lowest common multiple of 977,344,240,490,398 is 98315822640.

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.

977 x 344 x 240 x 490 x 398 = 15730531622400

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.

977 : 1, 977

344 : 1, 2, 4, 8, 43, 86, 172, 344

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,344,240,490,398, is 1.

Now, the common factors can be found like this.

977:977

344:2x 2x 2x 43

240:2x 2x 2x 2x 3x 5

490:2x 5x 7x 7

398:2x 199

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 2x 2x 5 = 160

Therefore, the value for common factors is 160.

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 = 15730531622400/(1x160)

LCM = 15730531622400/160

LCM = 98315822640

Thus, we can understand that the LCM of 977,344,240,490,398 is 98315822640.
