Find LCM of 393,552,188,154,989 with Prime Factorization
| 2 | 393, 552, 188, 154, 989 |
| 2 | 393, 276, 94, 77, 989 |
| 3 | 393, 138, 47, 77, 989 |
| 23 | 131, 46, 47, 77, 989 |
| 131, 2, 47, 77, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 131 x 2 x 47 x 77 x 43 = 11252976504
Therefore, the lowest common multiple of 393,552,188,154,989 is 11252976504.
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.
393 x 552 x 188 x 154 x 989 = 6211643030208
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.
393 : 1, 3, 131, 393
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
188 : 1, 2, 4, 47, 94, 188
154 : 1, 2, 7, 11, 14, 22, 77, 154
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,552,188,154,989, is 1.
Now, the common factors can be found like this.
393:3x 131
552:2x 2x 2x 3x 23
188:2x 2x 47
154:2x 7x 11
989:23x 43
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 23 = 552
Therefore, the value for common factors is 552.
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 = 6211643030208/(1x552)
LCM = 6211643030208/552
LCM = 11252976504
Thus, we can understand that the LCM of 393,552,188,154,989 is 11252976504.
