Given numbers are 889,180,399,454,660

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

The LCM of 889,180,399,454,660 is 7591828860.

Find LCM of 889,180,399,454,660 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 127 x 3 x 19 x 227 x 11 = 7591828860

Therefore, the lowest common multiple of 889,180,399,454,660 is 7591828860.

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.

889 x 180 x 399 x 454 x 660 = 19131408727200

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.

889 : 1, 7, 127, 889

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

399 : 1, 3, 7, 19, 21, 57, 133, 399

454 : 1, 2, 227, 454

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,180,399,454,660, is 1.

Now, the common factors can be found like this.

889:7x 127

180:2x 2x 3x 3x 5

399:3x 7x 19

454:2x 227

660:2x 2x 3x 5x 11

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 3x 3x 5x 7 = 2520

Therefore, the value for common factors is 2520.

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 = 19131408727200/(1x2520)

LCM = 19131408727200/2520

LCM = 7591828860

Thus, we can understand that the LCM of 889,180,399,454,660 is 7591828860.
