Find LCM of 151,455,884,429,780 with Prime Factorization
| 2 | 151, 455, 884, 429, 780 |
| 2 | 151, 455, 442, 429, 390 |
| 3 | 151, 455, 221, 429, 195 |
| 5 | 151, 455, 221, 143, 65 |
| 13 | 151, 91, 221, 143, 13 |
| 151, 7, 17, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 151 x 7 x 17 x 11 x 1 = 154174020
Therefore, the lowest common multiple of 151,455,884,429,780 is 154174020.
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.
151 x 455 x 884 x 429 x 780 = 20323219316400
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.
151 : 1, 151
455 : 1, 5, 7, 13, 35, 65, 91, 455
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
429 : 1, 3, 11, 13, 33, 39, 143, 429
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 151,455,884,429,780, is 1.
Now, the common factors can be found like this.
151:151
455:5x 7x 13
884:2x 2x 13x 17
429:3x 11x 13
780:2x 2x 3x 5x 13
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 3x 5x 13x 13x 13 = 131820
Therefore, the value for common factors is 131820.
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 = 20323219316400/(1x131820)
LCM = 20323219316400/131820
LCM = 154174020
Thus, we can understand that the LCM of 151,455,884,429,780 is 154174020.
