Given numbers are 771,391,489,906,446

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

The LCM of 771,391,489,906,446 is 3309257378478.

Find LCM of 771,391,489,906,446 with Prime Factorization

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

2 x 3 x 257 x 391 x 163 x 151 x 223 = 3309257378478

Therefore, the lowest common multiple of 771,391,489,906,446 is 3309257378478.

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.

771 x 391 x 489 x 906 x 446 = 59566632812604

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.

771 : 1, 3, 257, 771

391 : 1, 17, 23, 391

489 : 1, 3, 163, 489

906 : 1, 2, 3, 6, 151, 302, 453, 906

446 : 1, 2, 223, 446

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,391,489,906,446, is 1.

Now, the common factors can be found like this.

771:3x 257

391:17x 23

489:3x 163

906:2x 3x 151

446:2x 223

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 59566632812604/(1x18)

LCM = 59566632812604/18

LCM = 3309257378478

Thus, we can understand that the LCM of 771,391,489,906,446 is 3309257378478.
