Given numbers are 4170,7690

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

The LCM of 4170,7690 is 3206730.

Find LCM of 4170,7690 with Prime Factorization

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

2 x 5 x 417 x 769 = 3206730

Therefore, the lowest common multiple of 4170,7690 is 3206730.

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.

4170 x 7690 = 32067300

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.

4170 : 1, 2, 3, 5, 6, 10, 15, 30, 139, 278, 417, 695, 834, 1390, 2085, 4170

7690 : 1, 2, 5, 10, 769, 1538, 3845, 7690

10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4170,7690, is 10.

Now, the common factors can be found like this.

4170:2x 3x 5x 139

7690:2x 5x 769

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

= 1

Therefore, the value for common factors is 1.

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 = 32067300/(10x1)

LCM = 32067300/10

LCM = 3206730

Thus, we can understand that the LCM of 4170,7690 is 3206730.

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