Find LCM of 165,963,285,384,770 with Prime Factorization
| 2 | 165, 963, 285, 384, 770 |
| 3 | 165, 963, 285, 192, 385 |
| 5 | 55, 321, 95, 64, 385 |
| 11 | 11, 321, 19, 64, 77 |
| 1, 321, 19, 64, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 1 x 321 x 19 x 64 x 7 = 901676160
Therefore, the lowest common multiple of 165,963,285,384,770 is 901676160.
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.
165 x 963 x 285 x 384 x 770 = 13389890976000
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
963 : 1, 3, 9, 107, 321, 963
285 : 1, 3, 5, 15, 19, 57, 95, 285
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,963,285,384,770, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
963:3x 3x 107
285:3x 5x 19
384:2x 2x 2x 2x 2x 2x 2x 3
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5x 11 = 14850
Therefore, the value for common factors is 14850.
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 = 13389890976000/(1x14850)
LCM = 13389890976000/14850
LCM = 901676160
Thus, we can understand that the LCM of 165,963,285,384,770 is 901676160.
