Find LCM of 131,378,945,975 with Prime Factorization
| 3 | 131, 378, 945, 975 |
| 3 | 131, 126, 315, 325 |
| 3 | 131, 42, 105, 325 |
| 5 | 131, 14, 35, 325 |
| 7 | 131, 14, 7, 65 |
| 131, 2, 1, 65 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 7 x 131 x 2 x 1 x 65 = 16093350
Therefore, the lowest common multiple of 131,378,945,975 is 16093350.
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.
131 x 378 x 945 x 975 = 45624647250
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.
131 : 1, 131
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,378,945,975, is 1.
Now, the common factors can be found like this.
131:131
378:2x 3x 3x 3x 7
945:3x 3x 3x 5x 7
975:3x 5x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 7 = 2835
Therefore, the value for common factors is 2835.
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 = 45624647250/(1x2835)
LCM = 45624647250/2835
LCM = 16093350
Thus, we can understand that the LCM of 131,378,945,975 is 16093350.
