Given numbers are 721,713,618,863

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

The LCM of 721,713,618,863 is 2661869994.

Find LCM of 721,713,618,863 with Prime Factorization

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

103 x 7 x 713 x 6 x 863 = 2661869994

Therefore, the lowest common multiple of 721,713,618,863 is 2661869994.

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.

721 x 713 x 618 x 863 = 274172609382

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.

721 : 1, 7, 103, 721

713 : 1, 23, 31, 713

618 : 1, 2, 3, 6, 103, 206, 309, 618

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,713,618,863, is 1.

Now, the common factors can be found like this.

721:7x 103

713:23x 31

618:2x 3x 103

863:863

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

103 = 103

Therefore, the value for common factors is 103.

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 = 274172609382/(1x103)

LCM = 274172609382/103

LCM = 2661869994

Thus, we can understand that the LCM of 721,713,618,863 is 2661869994.
