Given numbers are 212,138,346,155

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

The LCM of 212,138,346,155 is 392249820.

Find LCM of 212,138,346,155 with Prime Factorization

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

2 x 106 x 69 x 173 x 155 = 392249820

Therefore, the lowest common multiple of 212,138,346,155 is 392249820.

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.

212 x 138 x 346 x 155 = 1568999280

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.

212 : 1, 2, 4, 53, 106, 212

138 : 1, 2, 3, 6, 23, 46, 69, 138

346 : 1, 2, 173, 346

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,138,346,155, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

138:2x 3x 23

346:2x 173

155:5x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 1568999280/(1x4)

LCM = 1568999280/4

LCM = 392249820

Thus, we can understand that the LCM of 212,138,346,155 is 392249820.
