Given numbers are 390,779,254

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

The LCM of 390,779,254 is 38583870.

Find LCM of 390,779,254 with Prime Factorization

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

2 x 195 x 779 x 127 = 38583870

Therefore, the lowest common multiple of 390,779,254 is 38583870.

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.

390 x 779 x 254 = 77167740

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

779 : 1, 19, 41, 779

254 : 1, 2, 127, 254

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,779,254, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

779:19x 41

254:2x 127

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 77167740/(1x2)

LCM = 77167740/2

LCM = 38583870

Thus, we can understand that the LCM of 390,779,254 is 38583870.

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

• LCM of 439, 563, 725
