Find LCM of 646,191,228,447,476 with Prime Factorization
| 2 | 646, 191, 228, 447, 476 |
| 2 | 323, 191, 114, 447, 238 |
| 3 | 323, 191, 57, 447, 119 |
| 17 | 323, 191, 19, 149, 119 |
| 19 | 19, 191, 19, 149, 7 |
| 1, 191, 1, 149, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 19 x 1 x 191 x 1 x 149 x 7 = 772149588
Therefore, the lowest common multiple of 646,191,228,447,476 is 772149588.
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.
646 x 191 x 228 x 447 x 476 = 5985703606176
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
191 : 1, 191
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
447 : 1, 3, 149, 447
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,191,228,447,476, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
191:191
228:2x 2x 3x 19
447:3x 149
476:2x 2x 7x 17
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 17x 19 = 7752
Therefore, the value for common factors is 7752.
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 = 5985703606176/(1x7752)
LCM = 5985703606176/7752
LCM = 772149588
Thus, we can understand that the LCM of 646,191,228,447,476 is 772149588.
