Given numbers are 138,214,217,155

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

The LCM of 138,214,217,155 is 16021110.

Find LCM of 138,214,217,155 with Prime Factorization

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

2 x 31 x 69 x 107 x 7 x 5 = 16021110

Therefore, the lowest common multiple of 138,214,217,155 is 16021110.

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.

138 x 214 x 217 x 155 = 993308820

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.

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

214 : 1, 2, 107, 214

217 : 1, 7, 31, 217

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,214,217,155, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

214:2x 107

217:7x 31

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 31 = 62

Therefore, the value for common factors is 62.

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 = 993308820/(1x62)

LCM = 993308820/62

LCM = 16021110

Thus, we can understand that the LCM of 138,214,217,155 is 16021110.
