Find LCM of 115,211,423,640,810 with Prime Factorization
2 | 115, 211, 423, 640, 810 |
3 | 115, 211, 423, 320, 405 |
3 | 115, 211, 141, 320, 135 |
5 | 115, 211, 47, 320, 45 |
23, 211, 47, 64, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 23 x 211 x 47 x 64 x 9 = 11824237440
Therefore, the lowest common multiple of 115,211,423,640,810 is 11824237440.
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.
115 x 211 x 423 x 640 x 810 = 5320906848000
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.
115 : 1, 5, 23, 115
211 : 1, 211
423 : 1, 3, 9, 47, 141, 423
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,211,423,640,810, is 1.
Now, the common factors can be found like this.
115:5x 23
211:211
423:3x 3x 47
640:2x 2x 2x 2x 2x 2x 2x 5
810:2x 3x 3x 3x 3x 5
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 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 5320906848000/(1x450)
LCM = 5320906848000/450
LCM = 11824237440
Thus, we can understand that the LCM of 115,211,423,640,810 is 11824237440.
