Given numbers are 2907,7809

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

The LCM of 2907,7809 is 398259.

Find LCM of 2907,7809 with Prime Factorization

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

3 x 19 x 51 x 137 = 398259

Therefore, the lowest common multiple of 2907,7809 is 398259.

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.

2907 x 7809 = 22700763

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.

2907 : 1, 3, 9, 17, 19, 51, 57, 153, 171, 323, 969, 2907

7809 : 1, 3, 19, 57, 137, 411, 2603, 7809

57 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2907,7809, is 57.

Now, the common factors can be found like this.

2907:3x 3x 17x 19

7809:3x 19x 137

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 = 22700763/(57x1)

LCM = 22700763/57

LCM = 398259

Thus, we can understand that the LCM of 2907,7809 is 398259.
