Given numbers are 765,493,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,493,170 is 44370.
Find LCM of 765,493,170 with Prime Factorization
| 5 | 765, 493, 170 |
| 17 | 153, 493, 34 |
| 9, 29, 2 |
Multiply the prime numbers at the bottom and the left side.
5 x 17 x 9 x 29 x 2 = 44370
Therefore, the lowest common multiple of 765,493,170 is 44370.
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.
765 x 493 x 170 = 64114650
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
493 : 1, 17, 29, 493
170 : 1, 2, 5, 10, 17, 34, 85, 170
17 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,493,170, is 17.
Now, the common factors can be found like this.
765:3x 3x 5x 17
493:17x 29
170:2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 17 = 85
Therefore, the value for common factors is 85.
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 = 64114650/(17x85)
LCM = 64114650/1445
LCM = 44370
Thus, we can understand that the LCM of 765,493,170 is 44370.
