Given numbers are 720,134,228,457

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

The LCM of 720,134,228,457 is 418867920.

Find LCM of 720,134,228,457 with Prime Factorization

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

2 x 2 x 3 x 60 x 67 x 19 x 457 = 418867920

Therefore, the lowest common multiple of 720,134,228,457 is 418867920.

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 134 x 228 x 457 = 10052830080

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

134 : 1, 2, 67, 134

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,134,228,457, is 1.

Now, the common factors can be found like this.

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

134:2x 67

228:2x 2x 3x 19

457:457

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 10052830080/(1x24)

LCM = 10052830080/24

LCM = 418867920

Thus, we can understand that the LCM of 720,134,228,457 is 418867920.
