Find LCM of 881,915,251,138,990 with Prime Factorization
2 | 881, 915, 251, 138, 990 |
3 | 881, 915, 251, 69, 495 |
5 | 881, 305, 251, 23, 165 |
881, 61, 251, 23, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 881 x 61 x 251 x 23 x 33 = 307144325070
Therefore, the lowest common multiple of 881,915,251,138,990 is 307144325070.
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.
881 x 915 x 251 x 138 x 990 = 27642989256300
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.
881 : 1, 881
915 : 1, 3, 5, 15, 61, 183, 305, 915
251 : 1, 251
138 : 1, 2, 3, 6, 23, 46, 69, 138
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 881,915,251,138,990, is 1.
Now, the common factors can be found like this.
881:881
915:3x 5x 61
251:251
138:2x 3x 23
990:2x 3x 3x 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 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 27642989256300/(1x90)
LCM = 27642989256300/90
LCM = 307144325070
Thus, we can understand that the LCM of 881,915,251,138,990 is 307144325070.
