Given numbers are 1251,2109

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

The LCM of 1251,2109 is 879453.

Find LCM of 1251,2109 with Prime Factorization

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

3 x 417 x 703 = 879453

Therefore, the lowest common multiple of 1251,2109 is 879453.

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.

1251 x 2109 = 2638359

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.

1251 : 1, 3, 9, 139, 417, 1251

2109 : 1, 3, 19, 37, 57, 111, 703, 2109

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1251,2109, is 3.

Now, the common factors can be found like this.

1251:3x 3x 139

2109:3x 19x 37

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 = 2638359/(3x1)

LCM = 2638359/3

LCM = 879453

Thus, we can understand that the LCM of 1251,2109 is 879453.
