Given numbers are 156,55,842

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

The LCM of 156,55,842 is 3612180.

Find LCM of 156,55,842 with Prime Factorization

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

2 x 78 x 55 x 421 = 3612180

Therefore, the lowest common multiple of 156,55,842 is 3612180.

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.

156 x 55 x 842 = 7224360

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.

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

55 : 1, 5, 11, 55

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,55,842, is 1.

Now, the common factors can be found like this.

156:2x 2x 3x 13

55:5x 11

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 = 7224360/(1x2)

LCM = 7224360/2

LCM = 3612180

Thus, we can understand that the LCM of 156,55,842 is 3612180.

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

• LCM of 989, 89, 666
• LCM of 786, 75, 238
