Given numbers are 721,452,734,642

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

The LCM of 721,452,734,642 is 38392358844.

Find LCM of 721,452,734,642 with Prime Factorization

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

2 x 721 x 226 x 367 x 321 = 38392358844

Therefore, the lowest common multiple of 721,452,734,642 is 38392358844.

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 452 x 734 x 642 = 153569435376

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

452 : 1, 2, 4, 113, 226, 452

734 : 1, 2, 367, 734

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,452,734,642, is 1.

Now, the common factors can be found like this.

721:7x 103

452:2x 2x 113

734:2x 367

642:2x 3x 107

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 = 153569435376/(1x4)

LCM = 153569435376/4

LCM = 38392358844

Thus, we can understand that the LCM of 721,452,734,642 is 38392358844.
