Given numbers are 681,659,299,689

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

The LCM of 681,659,299,689 is 7111800813.

Find LCM of 681,659,299,689 with Prime Factorization

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

13 x 681 x 659 x 23 x 53 = 7111800813

Therefore, the lowest common multiple of 681,659,299,689 is 7111800813.

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.

681 x 659 x 299 x 689 = 92453410569

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.

681 : 1, 3, 227, 681

659 : 1, 659

299 : 1, 13, 23, 299

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,659,299,689, is 1.

Now, the common factors can be found like this.

681:3x 227

659:659

299:13x 23

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.

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 = 92453410569/(1x13)

LCM = 92453410569/13

LCM = 7111800813

Thus, we can understand that the LCM of 681,659,299,689 is 7111800813.
