Given numbers are 3154,7842

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

The LCM of 3154,7842 is 12366834.

Find LCM of 3154,7842 with Prime Factorization

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

2 x 1577 x 3921 = 12366834

Therefore, the lowest common multiple of 3154,7842 is 12366834.

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.

3154 x 7842 = 24733668

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.

3154 : 1, 2, 19, 38, 83, 166, 1577, 3154

7842 : 1, 2, 3, 6, 1307, 2614, 3921, 7842

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3154,7842, is 2.

Now, the common factors can be found like this.

3154:2x 19x 83

7842:2x 3x 1307

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 = 24733668/(2x1)

LCM = 24733668/2

LCM = 12366834

Thus, we can understand that the LCM of 3154,7842 is 12366834.

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

• LCM of 4272, 5937
• LCM of 2738, 7985
