Given numbers are 678,143,115,161

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

The LCM of 678,143,115,161 is 78047970.

Find LCM of 678,143,115,161 with Prime Factorization

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

23 x 678 x 143 x 5 x 7 = 78047970

Therefore, the lowest common multiple of 678,143,115,161 is 78047970.

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.

678 x 143 x 115 x 161 = 1795103310

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

143 : 1, 11, 13, 143

115 : 1, 5, 23, 115

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,143,115,161, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

143:11x 13

115:5x 23

161:7x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 1795103310/(1x23)

LCM = 1795103310/23

LCM = 78047970

Thus, we can understand that the LCM of 678,143,115,161 is 78047970.
