Given numbers are 622,155,378

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

The LCM of 622,155,378 is 18221490.

Find LCM of 622,155,378 with Prime Factorization

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

2 x 311 x 155 x 189 = 18221490

Therefore, the lowest common multiple of 622,155,378 is 18221490.

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.

622 x 155 x 378 = 36442980

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.

622 : 1, 2, 311, 622

155 : 1, 5, 31, 155

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,155,378, is 1.

Now, the common factors can be found like this.

622:2x 311

155:5x 31

378:2x 3x 3x 3x 7

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 = 36442980/(1x2)

LCM = 36442980/2

LCM = 18221490

Thus, we can understand that the LCM of 622,155,378 is 18221490.

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

• LCM of 363, 903, 394
