Given numbers are 513,923,689,691

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

The LCM of 513,923,689,691 is 17340953877.

Find LCM of 513,923,689,691 with Prime Factorization

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

13 x 513 x 71 x 53 x 691 = 17340953877

Therefore, the lowest common multiple of 513,923,689,691 is 17340953877.

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.

513 x 923 x 689 x 691 = 225432400401

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.

513 : 1, 3, 9, 19, 27, 57, 171, 513

923 : 1, 13, 71, 923

689 : 1, 13, 53, 689

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,923,689,691, is 1.

Now, the common factors can be found like this.

513:3x 3x 3x 19

923:13x 71

689:13x 53

691:691

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 = 225432400401/(1x13)

LCM = 225432400401/13

LCM = 17340953877

Thus, we can understand that the LCM of 513,923,689,691 is 17340953877.
