Given numbers are 811,760,632,180,689

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

The LCM of 811,760,632,180,689 is 301941820440.

Find LCM of 811,760,632,180,689 with Prime Factorization

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

2 x 2 x 2 x 5 x 811 x 19 x 79 x 9 x 689 = 301941820440

Therefore, the lowest common multiple of 811,760,632,180,689 is 301941820440.

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.

811 x 760 x 632 x 180 x 689 = 48310691270400

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.

811 : 1, 811

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

632 : 1, 2, 4, 8, 79, 158, 316, 632

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

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,760,632,180,689, is 1.

Now, the common factors can be found like this.

811:811

760:2x 2x 2x 5x 19

632:2x 2x 2x 79

180:2x 2x 3x 3x 5

689:13x 53

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 2x 5 = 160

Therefore, the value for common factors is 160.

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 = 48310691270400/(1x160)

LCM = 48310691270400/160

LCM = 301941820440

Thus, we can understand that the LCM of 811,760,632,180,689 is 301941820440.
