Given numbers are 7491,1251

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

The LCM of 7491,1251 is 3123747.

Find LCM of 7491,1251 with Prime Factorization

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

3 x 2497 x 417 = 3123747

Therefore, the lowest common multiple of 7491,1251 is 3123747.

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.

7491 x 1251 = 9371241

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.

7491 : 1, 3, 11, 33, 227, 681, 2497, 7491

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7491,1251, is 3.

Now, the common factors can be found like this.

7491:3x 11x 227

1251:3x 3x 139

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 = 9371241/(3x1)

LCM = 9371241/3

LCM = 3123747

Thus, we can understand that the LCM of 7491,1251 is 3123747.
