Given numbers are 397,438,346

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

The LCM of 397,438,346 is 30082278.

Find LCM of 397,438,346 with Prime Factorization

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

2 x 397 x 219 x 173 = 30082278

Therefore, the lowest common multiple of 397,438,346 is 30082278.

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.

397 x 438 x 346 = 60164556

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.

397 : 1, 397

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

346 : 1, 2, 173, 346

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,438,346, is 1.

Now, the common factors can be found like this.

397:397

438:2x 3x 73

346:2x 173

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 = 60164556/(1x2)

LCM = 60164556/2

LCM = 30082278

Thus, we can understand that the LCM of 397,438,346 is 30082278.

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

• LCM of 608, 499, 944
• LCM of 171, 554, 357
