Find LCM of 430,258,312,278,415 with Prime Factorization
| 2 | 430, 258, 312, 278, 415 |
| 3 | 215, 129, 156, 139, 415 |
| 5 | 215, 43, 52, 139, 415 |
| 43 | 43, 43, 52, 139, 83 |
| 1, 1, 52, 139, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 1 x 1 x 52 x 139 x 83 = 773901960
Therefore, the lowest common multiple of 430,258,312,278,415 is 773901960.
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.
430 x 258 x 312 x 278 x 415 = 3993334113600
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
258 : 1, 2, 3, 6, 43, 86, 129, 258
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
278 : 1, 2, 139, 278
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,258,312,278,415, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
258:2x 3x 43
312:2x 2x 2x 3x 13
278:2x 139
415:5x 83
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 5x 43 = 5160
Therefore, the value for common factors is 5160.
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 = 3993334113600/(1x5160)
LCM = 3993334113600/5160
LCM = 773901960
Thus, we can understand that the LCM of 430,258,312,278,415 is 773901960.
