Find LCM of 769,165,324,894,420 with Prime Factorization
| 2 | 769, 165, 324, 894, 420 |
| 2 | 769, 165, 162, 447, 210 |
| 3 | 769, 165, 81, 447, 105 |
| 5 | 769, 55, 27, 149, 35 |
| 769, 11, 27, 149, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 769 x 11 x 27 x 149 x 7 = 14292833940
Therefore, the lowest common multiple of 769,165,324,894,420 is 14292833940.
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.
769 x 165 x 324 x 894 x 420 = 15436260655200
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.
769 : 1, 769
165 : 1, 3, 5, 11, 15, 33, 55, 165
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
894 : 1, 2, 3, 6, 149, 298, 447, 894
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,165,324,894,420, is 1.
Now, the common factors can be found like this.
769:769
165:3x 5x 11
324:2x 2x 3x 3x 3x 3
894:2x 3x 149
420:2x 2x 3x 5x 7
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 2x 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 15436260655200/(1x1080)
LCM = 15436260655200/1080
LCM = 14292833940
Thus, we can understand that the LCM of 769,165,324,894,420 is 14292833940.
