Given numbers are 1628,4138

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

The LCM of 1628,4138 is 3368332.

Find LCM of 1628,4138 with Prime Factorization

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

2 x 814 x 2069 = 3368332

Therefore, the lowest common multiple of 1628,4138 is 3368332.

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.

1628 x 4138 = 6736664

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.

1628 : 1, 2, 4, 11, 22, 37, 44, 74, 148, 407, 814, 1628

4138 : 1, 2, 2069, 4138

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1628,4138, is 2.

Now, the common factors can be found like this.

1628:2x 2x 11x 37

4138:2x 2069

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 = 6736664/(2x1)

LCM = 6736664/2

LCM = 3368332

Thus, we can understand that the LCM of 1628,4138 is 3368332.

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

• LCM of 8331, 1447
• LCM of 5745, 1922
