Given numbers are 7642,5018

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

The LCM of 7642,5018 is 19173778.

Find LCM of 7642,5018 with Prime Factorization

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

2 x 3821 x 2509 = 19173778

Therefore, the lowest common multiple of 7642,5018 is 19173778.

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.

7642 x 5018 = 38347556

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.

7642 : 1, 2, 3821, 7642

5018 : 1, 2, 13, 26, 193, 386, 2509, 5018

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7642,5018, is 2.

Now, the common factors can be found like this.

7642:2x 3821

5018:2x 13x 193

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 = 38347556/(2x1)

LCM = 38347556/2

LCM = 19173778

Thus, we can understand that the LCM of 7642,5018 is 19173778.

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

• LCM of 1864, 8341
