Given numbers are 170,181,905,770,302
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 170,181,905,770,302 is 357762790.
Find LCM of 170,181,905,770,302 with Prime Factorization
| 2 | 170, 181, 905, 770, 302 |
| 5 | 85, 181, 905, 385, 151 |
| 181 | 17, 181, 181, 77, 151 |
| 17, 1, 1, 77, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 181 x 17 x 1 x 1 x 77 x 151 = 357762790
Therefore, the lowest common multiple of 170,181,905,770,302 is 357762790.
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 181 x 905 x 770 x 302 = 6475506499000
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
181 : 1, 181
905 : 1, 5, 181, 905
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
302 : 1, 2, 151, 302
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,181,905,770,302, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
181:181
905:5x 181
770:2x 5x 7x 11
302:2x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5x 181 = 18100
Therefore, the value for common factors is 18100.
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 = 6475506499000/(1x18100)
LCM = 6475506499000/18100
LCM = 357762790
Thus, we can understand that the LCM of 170,181,905,770,302 is 357762790.
