Find LCM of 390,219,979,580,146 with Prime Factorization
| 2 | 390, 219, 979, 580, 146 |
| 3 | 195, 219, 979, 290, 73 |
| 5 | 65, 73, 979, 290, 73 |
| 73 | 13, 73, 979, 58, 73 |
| 13, 1, 979, 58, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 73 x 13 x 1 x 979 x 58 x 1 = 1616583540
Therefore, the lowest common multiple of 390,219,979,580,146 is 1616583540.
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.
390 x 219 x 979 x 580 x 146 = 7080635905200
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
219 : 1, 3, 73, 219
979 : 1, 11, 89, 979
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,219,979,580,146, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
219:3x 73
979:11x 89
580:2x 2x 5x 29
146:2x 73
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 73 = 4380
Therefore, the value for common factors is 4380.
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 = 7080635905200/(1x4380)
LCM = 7080635905200/4380
LCM = 1616583540
Thus, we can understand that the LCM of 390,219,979,580,146 is 1616583540.
