Given numbers are 3890,4402

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

The LCM of 3890,4402 is 8561890.

Find LCM of 3890,4402 with Prime Factorization

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

2 x 1945 x 2201 = 8561890

Therefore, the lowest common multiple of 3890,4402 is 8561890.

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.

3890 x 4402 = 17123780

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.

3890 : 1, 2, 5, 10, 389, 778, 1945, 3890

4402 : 1, 2, 31, 62, 71, 142, 2201, 4402

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3890,4402, is 2.

Now, the common factors can be found like this.

3890:2x 5x 389

4402:2x 31x 71

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 = 17123780/(2x1)

LCM = 17123780/2

LCM = 8561890

Thus, we can understand that the LCM of 3890,4402 is 8561890.

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

• LCM of 6499, 1320
• LCM of 2305, 5769
