Find LCM of 228,995,990,407 with Prime Factorization
| 2 | 228, 995, 990, 407 |
| 3 | 114, 995, 495, 407 |
| 5 | 38, 995, 165, 407 |
| 11 | 38, 199, 33, 407 |
| 38, 199, 3, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 38 x 199 x 3 x 37 = 276996060
Therefore, the lowest common multiple of 228,995,990,407 is 276996060.
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.
228 x 995 x 990 x 407 = 91408699800
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
995 : 1, 5, 199, 995
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,995,990,407, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
995:5x 199
990:2x 3x 3x 5x 11
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 91408699800/(1x330)
LCM = 91408699800/330
LCM = 276996060
Thus, we can understand that the LCM of 228,995,990,407 is 276996060.
