Given numbers are 298,45,670

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

The LCM of 298,45,670 is 898470.

Find LCM of 298,45,670 with Prime Factorization

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

2 x 5 x 149 x 9 x 67 = 898470

Therefore, the lowest common multiple of 298,45,670 is 898470.

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.

298 x 45 x 670 = 8984700

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.

298 : 1, 2, 149, 298

45 : 1, 3, 5, 9, 15, 45

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,45,670, is 1.

Now, the common factors can be found like this.

298:2x 149

45:3x 3x 5

670:2x 5x 67

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 = 8984700/(1x10)

LCM = 8984700/10

LCM = 898470

Thus, we can understand that the LCM of 298,45,670 is 898470.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 644, 61, 125
• LCM of 229, 18, 468
