Given numbers are 156,742,117,305,173

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

The LCM of 156,742,117,305,173 is 9161481420.

Find LCM of 156,742,117,305,173 with Prime Factorization

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

2 x 3 x 13 x 2 x 371 x 3 x 305 x 173 = 9161481420

Therefore, the lowest common multiple of 156,742,117,305,173 is 9161481420.

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 742 x 117 x 305 x 173 = 714595550760

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

742 : 1, 2, 7, 14, 53, 106, 371, 742

117 : 1, 3, 9, 13, 39, 117

305 : 1, 5, 61, 305

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,742,117,305,173, is 1.

Now, the common factors can be found like this.

156:2x 2x 3x 13

742:2x 7x 53

117:3x 3x 13

305:5x 61

173:173

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

2x 3x 13 = 78

Therefore, the value for common factors is 78.

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 = 714595550760/(1x78)

LCM = 714595550760/78

LCM = 9161481420

Thus, we can understand that the LCM of 156,742,117,305,173 is 9161481420.
