Given numbers are 715,646,796,862

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

The LCM of 715,646,796,862 is 79231686820.

Find LCM of 715,646,796,862 with Prime Factorization

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

2 x 715 x 323 x 398 x 431 = 79231686820

Therefore, the lowest common multiple of 715,646,796,862 is 79231686820.

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.

715 x 646 x 796 x 862 = 316926747280

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.

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

796 : 1, 2, 4, 199, 398, 796

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,646,796,862, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

646:2x 17x 19

796:2x 2x 199

862:2x 431

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 316926747280/(1x4)

LCM = 316926747280/4

LCM = 79231686820

Thus, we can understand that the LCM of 715,646,796,862 is 79231686820.
