Given numbers are 431,438,254

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

The LCM of 431,438,254 is 23974806.

Find LCM of 431,438,254 with Prime Factorization

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

2 x 431 x 219 x 127 = 23974806

Therefore, the lowest common multiple of 431,438,254 is 23974806.

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.

431 x 438 x 254 = 47949612

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.

431 : 1, 431

438 : 1, 2, 3, 6, 73, 146, 219, 438

254 : 1, 2, 127, 254

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,438,254, is 1.

Now, the common factors can be found like this.

431:431

438:2x 3x 73

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 = 47949612/(1x2)

LCM = 47949612/2

LCM = 23974806

Thus, we can understand that the LCM of 431,438,254 is 23974806.

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

• LCM of 374, 682, 872
• LCM of 934, 385, 727
