Given numbers are 865,925,421

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

The LCM of 865,925,421 is 67370525.

Find LCM of 865,925,421 with Prime Factorization

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

5 x 173 x 185 x 421 = 67370525

Therefore, the lowest common multiple of 865,925,421 is 67370525.

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.

865 x 925 x 421 = 336852625

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.

865 : 1, 5, 173, 865

925 : 1, 5, 25, 37, 185, 925

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,925,421, is 1.

Now, the common factors can be found like this.

865:5x 173

925:5x 5x 37

421:421

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

5 = 5

Therefore, the value for common factors is 5.

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 = 336852625/(1x5)

LCM = 336852625/5

LCM = 67370525

Thus, we can understand that the LCM of 865,925,421 is 67370525.

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

• LCM of 137, 317, 935
• LCM of 648, 739, 157
