Given numbers are 877,912,321,198,390

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

The LCM of 877,912,321,198,390 is 183571605360.

Find LCM of 877,912,321,198,390 with Prime Factorization

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

2 x 3 x 877 x 152 x 107 x 33 x 65 = 183571605360

Therefore, the lowest common multiple of 877,912,321,198,390 is 183571605360.

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.

877 x 912 x 321 x 198 x 390 = 19825733378880

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.

877 : 1, 877

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

321 : 1, 3, 107, 321

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 877,912,321,198,390, is 1.

Now, the common factors can be found like this.

877:877

912:2x 2x 2x 2x 3x 19

321:3x 107

198:2x 3x 3x 11

390:2x 3x 5x 13

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 19825733378880/(1x108)

LCM = 19825733378880/108

LCM = 183571605360

Thus, we can understand that the LCM of 877,912,321,198,390 is 183571605360.
