Find LCM of 282,791,390,715,390 with Prime Factorization
| 2 | 282, 791, 390, 715, 390 |
| 3 | 141, 791, 195, 715, 195 |
| 5 | 47, 791, 65, 715, 65 |
| 13 | 47, 791, 13, 143, 13 |
| 47, 791, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 47 x 791 x 1 x 11 x 1 = 159489330
Therefore, the lowest common multiple of 282,791,390,715,390 is 159489330.
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.
282 x 791 x 390 x 715 x 390 = 24258327093000
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
791 : 1, 7, 113, 791
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
715 : 1, 5, 11, 13, 55, 65, 143, 715
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,791,390,715,390, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
791:7x 113
390:2x 3x 5x 13
715:5x 11x 13
390:2x 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 3x 5x 5x 13x 13 = 152100
Therefore, the value for common factors is 152100.
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 = 24258327093000/(1x152100)
LCM = 24258327093000/152100
LCM = 159489330
Thus, we can understand that the LCM of 282,791,390,715,390 is 159489330.
