Given numbers are 720,325,197,615,418

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

The LCM of 720,325,197,615,418 is 79002752400.

Find LCM of 720,325,197,615,418 with Prime Factorization

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

2 x 3 x 5 x 24 x 65 x 197 x 41 x 209 = 79002752400

Therefore, the lowest common multiple of 720,325,197,615,418 is 79002752400.

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.

720 x 325 x 197 x 615 x 418 = 11850412860000

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.

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

325 : 1, 5, 13, 25, 65, 325

197 : 1, 197

615 : 1, 3, 5, 15, 41, 123, 205, 615

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,325,197,615,418, is 1.

Now, the common factors can be found like this.

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

325:5x 5x 13

197:197

615:3x 5x 41

418:2x 11x 19

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

2x 3x 5x 5 = 150

Therefore, the value for common factors is 150.

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 = 11850412860000/(1x150)

LCM = 11850412860000/150

LCM = 79002752400

Thus, we can understand that the LCM of 720,325,197,615,418 is 79002752400.
