Find LCM of 856,456,741,949 with Prime Factorization
| 2 | 856, 456, 741, 949 |
| 2 | 428, 228, 741, 949 |
| 2 | 214, 114, 741, 949 |
| 3 | 107, 57, 741, 949 |
| 13 | 107, 19, 247, 949 |
| 19 | 107, 19, 19, 73 |
| 107, 1, 1, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 19 x 107 x 1 x 1 x 73 = 46303608
Therefore, the lowest common multiple of 856,456,741,949 is 46303608.
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.
856 x 456 x 741 x 949 = 274487788224
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
741 : 1, 3, 13, 19, 39, 57, 247, 741
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,456,741,949, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
456:2x 2x 2x 3x 19
741:3x 13x 19
949:13x 73
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 13x 19 = 5928
Therefore, the value for common factors is 5928.
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 = 274487788224/(1x5928)
LCM = 274487788224/5928
LCM = 46303608
Thus, we can understand that the LCM of 856,456,741,949 is 46303608.
