Given numbers are 442,391,194,970

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

The LCM of 442,391,194,970 is 4930510.

Find LCM of 442,391,194,970 with Prime Factorization

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

2 x 17 x 97 x 13 x 23 x 1 x 5 = 4930510

Therefore, the lowest common multiple of 442,391,194,970 is 4930510.

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.

442 x 391 x 194 x 970 = 32521643960

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

391 : 1, 17, 23, 391

194 : 1, 2, 97, 194

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,391,194,970, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

391:17x 23

194:2x 97

970:2x 5x 97

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 17x 97 = 6596

Therefore, the value for common factors is 6596.

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 = 32521643960/(1x6596)

LCM = 32521643960/6596

LCM = 4930510

Thus, we can understand that the LCM of 442,391,194,970 is 4930510.
