Given numbers are 845,767,520,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,767,520,165 is 13161720.
Find LCM of 845,767,520,165 with Prime Factorization
| 5 | 845, 767, 520, 165 |
| 13 | 169, 767, 104, 33 |
| 13, 59, 8, 33 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 13 x 59 x 8 x 33 = 13161720
Therefore, the lowest common multiple of 845,767,520,165 is 13161720.
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.
845 x 767 x 520 x 165 = 55608267000
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.
845 : 1, 5, 13, 65, 169, 845
767 : 1, 13, 59, 767
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,767,520,165, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
767:13x 59
520:2x 2x 2x 5x 13
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 13x 13 = 4225
Therefore, the value for common factors is 4225.
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 = 55608267000/(1x4225)
LCM = 55608267000/4225
LCM = 13161720
Thus, we can understand that the LCM of 845,767,520,165 is 13161720.
