The LCM of 170,955,886,561 is 474678930.
Find LCM of 170,955,886,561 with Prime Factorization
| 2 | 170, 955, 886, 561 |
| 5 | 85, 955, 443, 561 |
| 17 | 17, 191, 443, 561 |
| 1, 191, 443, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 1 x 191 x 443 x 33 = 474678930
Therefore, the lowest common multiple of 170,955,886,561 is 474678930.
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.
170 x 955 x 886 x 561 = 80695418100
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
955 : 1, 5, 191, 955
886 : 1, 2, 443, 886
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,955,886,561, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
955:5x 191
886:2x 443
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 80695418100/(1x170)
LCM = 80695418100/170
LCM = 474678930
Thus, we can understand that the LCM of 170,955,886,561 is 474678930.
