Given numbers are 689,377,715,661

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

The LCM of 689,377,715,661 is 726409255.

Find LCM of 689,377,715,661 with Prime Factorization

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

13 x 53 x 29 x 55 x 661 = 726409255

Therefore, the lowest common multiple of 689,377,715,661 is 726409255.

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 377 x 715 x 661 = 122763164095

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

377 : 1, 13, 29, 377

715 : 1, 5, 11, 13, 55, 65, 143, 715

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,377,715,661, is 1.

Now, the common factors can be found like this.

689:13x 53

377:13x 29

715:5x 11x 13

661:661

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 122763164095/(1x169)

LCM = 122763164095/169

LCM = 726409255

Thus, we can understand that the LCM of 689,377,715,661 is 726409255.
