Given numbers are 470,197,720,278

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

The LCM of 470,197,720,278 is 926640720.

Find LCM of 470,197,720,278 with Prime Factorization

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

2 x 5 x 47 x 197 x 72 x 139 = 926640720

Therefore, the lowest common multiple of 470,197,720,278 is 926640720.

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.

470 x 197 x 720 x 278 = 18532814400

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.

470 : 1, 2, 5, 10, 47, 94, 235, 470

197 : 1, 197

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

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,197,720,278, is 1.

Now, the common factors can be found like this.

470:2x 5x 47

197:197

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

278:2x 139

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 18532814400/(1x20)

LCM = 18532814400/20

LCM = 926640720

Thus, we can understand that the LCM of 470,197,720,278 is 926640720.
