Given numbers are 681,715,748

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

The LCM of 681,715,748 is 33110220.

Find LCM of 681,715,748 with Prime Factorization

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

11 x 681 x 65 x 68 = 33110220

Therefore, the lowest common multiple of 681,715,748 is 33110220.

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 715 x 748 = 364212420

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

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

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,715,748, is 1.

Now, the common factors can be found like this.

681:3x 227

715:5x 11x 13

748:2x 2x 11x 17

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

11 = 11

Therefore, the value for common factors is 11.

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 = 364212420/(1x11)

LCM = 364212420/11

LCM = 33110220

Thus, we can understand that the LCM of 681,715,748 is 33110220.
