Given numbers are 689,706,129,767

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

The LCM of 689,706,129,767 is 3702249174.

Find LCM of 689,706,129,767 with Prime Factorization

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

13 x 53 x 706 x 129 x 59 = 3702249174

Therefore, the lowest common multiple of 689,706,129,767 is 3702249174.

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.

689 x 706 x 129 x 767 = 48129239262

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.

689 : 1, 13, 53, 689

706 : 1, 2, 353, 706

129 : 1, 3, 43, 129

767 : 1, 13, 59, 767

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,706,129,767, is 1.

Now, the common factors can be found like this.

689:13x 53

706:2x 353

129:3x 43

767:13x 59

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

13 = 13

Therefore, the value for common factors is 13.

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 = 48129239262/(1x13)

LCM = 48129239262/13

LCM = 3702249174

Thus, we can understand that the LCM of 689,706,129,767 is 3702249174.
