Given numbers are 326,713,720,445

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

The LCM of 326,713,720,445 is 7447313520.

Find LCM of 326,713,720,445 with Prime Factorization

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

2 x 5 x 163 x 713 x 72 x 89 = 7447313520

Therefore, the lowest common multiple of 326,713,720,445 is 7447313520.

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.

326 x 713 x 720 x 445 = 74473135200

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.

326 : 1, 2, 163, 326

713 : 1, 23, 31, 713

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,713,720,445, is 1.

Now, the common factors can be found like this.

326:2x 163

713:23x 31

720:2x 2x 2x 2x 3x 3x 5

445:5x 89

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 74473135200/(1x10)

LCM = 74473135200/10

LCM = 7447313520

Thus, we can understand that the LCM of 326,713,720,445 is 7447313520.
