Given numbers are 870,289,688,621,951

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

The LCM of 870,289,688,621,951 is 5675513298480.

Find LCM of 870,289,688,621,951 with Prime Factorization

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

2 x 3 x 145 x 289 x 344 x 207 x 317 = 5675513298480

Therefore, the lowest common multiple of 870,289,688,621,951 is 5675513298480.

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.

870 x 289 x 688 x 621 x 951 = 102159239372640

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.

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

289 : 1, 17, 289

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

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

951 : 1, 3, 317, 951

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,289,688,621,951, is 1.

Now, the common factors can be found like this.

870:2x 3x 5x 29

289:17x 17

688:2x 2x 2x 2x 43

621:3x 3x 3x 23

951:3x 317

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 = 102159239372640/(1x18)

LCM = 102159239372640/18

LCM = 5675513298480

Thus, we can understand that the LCM of 870,289,688,621,951 is 5675513298480.
