Given numbers are 721,143,772,290

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

The LCM of 721,143,772,290 is 11541349820.

Find LCM of 721,143,772,290 with Prime Factorization

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

2 x 721 x 143 x 386 x 145 = 11541349820

Therefore, the lowest common multiple of 721,143,772,290 is 11541349820.

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 143 x 772 x 290 = 23082699640

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

143 : 1, 11, 13, 143

772 : 1, 2, 4, 193, 386, 772

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,143,772,290, is 1.

Now, the common factors can be found like this.

721:7x 103

143:11x 13

772:2x 2x 193

290:2x 5x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 23082699640/(1x2)

LCM = 23082699640/2

LCM = 11541349820

Thus, we can understand that the LCM of 721,143,772,290 is 11541349820.
