Find LCM of 380,945,847,561 with Prime Factorization
3 | 380, 945, 847, 561 |
5 | 380, 315, 847, 187 |
7 | 76, 63, 847, 187 |
11 | 76, 9, 121, 187 |
76, 9, 11, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 11 x 76 x 9 x 11 x 17 = 147733740
Therefore, the lowest common multiple of 380,945,847,561 is 147733740.
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.
380 x 945 x 847 x 561 = 170632469700
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
847 : 1, 7, 11, 77, 121, 847
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,945,847,561, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
945:3x 3x 3x 5x 7
847:7x 11x 11
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 11 = 1155
Therefore, the value for common factors is 1155.
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 = 170632469700/(1x1155)
LCM = 170632469700/1155
LCM = 147733740
Thus, we can understand that the LCM of 380,945,847,561 is 147733740.
