Given numbers are 3971,7486

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

The LCM of 3971,7486 is 1564574.

Find LCM of 3971,7486 with Prime Factorization

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

19 x 209 x 394 = 1564574

Therefore, the lowest common multiple of 3971,7486 is 1564574.

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.

3971 x 7486 = 29726906

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.

3971 : 1, 11, 19, 209, 361, 3971

7486 : 1, 2, 19, 38, 197, 394, 3743, 7486

19 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3971,7486, is 19.

Now, the common factors can be found like this.

3971:11x 19x 19

7486:2x 19x 197

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 = 29726906/(19x1)

LCM = 29726906/19

LCM = 1564574

Thus, we can understand that the LCM of 3971,7486 is 1564574.
