Given numbers are 195,371,178,689

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

The LCM of 195,371,178,689 is 12877410.

Find LCM of 195,371,178,689 with Prime Factorization

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

13 x 53 x 15 x 7 x 178 x 1 = 12877410

Therefore, the lowest common multiple of 195,371,178,689 is 12877410.

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.

195 x 371 x 178 x 689 = 8872535490

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.

195 : 1, 3, 5, 13, 15, 39, 65, 195

371 : 1, 7, 53, 371

178 : 1, 2, 89, 178

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,371,178,689, is 1.

Now, the common factors can be found like this.

195:3x 5x 13

371:7x 53

178:2x 89

689:13x 53

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

13x 53 = 689

Therefore, the value for common factors is 689.

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 = 8872535490/(1x689)

LCM = 8872535490/689

LCM = 12877410

Thus, we can understand that the LCM of 195,371,178,689 is 12877410.
