Given numbers are 442,472,621,552,289

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

The LCM of 442,472,621,552,289 is 1101221784.

Find LCM of 442,472,621,552,289 with Prime Factorization

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

2 x 2 x 2 x 3 x 17 x 23 x 13 x 59 x 9 x 1 x 17 = 1101221784

Therefore, the lowest common multiple of 442,472,621,552,289 is 1101221784.

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 472 x 621 x 552 x 289 = 20667730442112

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

472 : 1, 2, 4, 8, 59, 118, 236, 472

621 : 1, 3, 9, 23, 27, 69, 207, 621

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,472,621,552,289, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

472:2x 2x 2x 59

621:3x 3x 3x 23

552:2x 2x 2x 3x 23

289:17x 17

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 3x 17x 23 = 18768

Therefore, the value for common factors is 18768.

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 = 20667730442112/(1x18768)

LCM = 20667730442112/18768

LCM = 1101221784

Thus, we can understand that the LCM of 442,472,621,552,289 is 1101221784.
