Find LCM of 368,745,985,816,220 with Prime Factorization
| 2 | 368, 745, 985, 816, 220 |
| 2 | 184, 745, 985, 408, 110 |
| 2 | 92, 745, 985, 204, 55 |
| 2 | 46, 745, 985, 102, 55 |
| 5 | 23, 745, 985, 51, 55 |
| 23, 149, 197, 51, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 23 x 149 x 197 x 51 x 11 = 30299340720
Therefore, the lowest common multiple of 368,745,985,816,220 is 30299340720.
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.
368 x 745 x 985 x 816 x 220 = 48478945152000
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
745 : 1, 5, 149, 745
985 : 1, 5, 197, 985
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,745,985,816,220, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
745:5x 149
985:5x 197
816:2x 2x 2x 2x 3x 17
220:2x 2x 5x 11
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 2x 2x 2x 5x 5 = 1600
Therefore, the value for common factors is 1600.
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 = 48478945152000/(1x1600)
LCM = 48478945152000/1600
LCM = 30299340720
Thus, we can understand that the LCM of 368,745,985,816,220 is 30299340720.
