Given numbers are 838,155,842

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

The LCM of 838,155,842 is 54683690.

Find LCM of 838,155,842 with Prime Factorization

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

2 x 419 x 155 x 421 = 54683690

Therefore, the lowest common multiple of 838,155,842 is 54683690.

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.

838 x 155 x 842 = 109367380

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.

838 : 1, 2, 419, 838

155 : 1, 5, 31, 155

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,155,842, is 1.

Now, the common factors can be found like this.

838:2x 419

155:5x 31

842:2x 421

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 = 109367380/(1x2)

LCM = 109367380/2

LCM = 54683690

Thus, we can understand that the LCM of 838,155,842 is 54683690.

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

• LCM of 223, 326, 746
• LCM of 906, 522, 378
• LCM of 455, 435, 664
