Find LCM of 856,773,221,476,455 with Prime Factorization
| 2 | 856, 773, 221, 476, 455 |
| 2 | 428, 773, 221, 238, 455 |
| 7 | 214, 773, 221, 119, 455 |
| 13 | 214, 773, 221, 17, 65 |
| 17 | 214, 773, 17, 17, 5 |
| 214, 773, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 17 x 214 x 773 x 1 x 1 x 5 = 5118156680
Therefore, the lowest common multiple of 856,773,221,476,455 is 5118156680.
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 773 x 221 x 476 x 455 = 31671153535840
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
773 : 1, 773
221 : 1, 13, 17, 221
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,773,221,476,455, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
773:773
221:13x 17
476:2x 2x 7x 17
455:5x 7x 13
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 7x 13x 17 = 6188
Therefore, the value for common factors is 6188.
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 = 31671153535840/(1x6188)
LCM = 31671153535840/6188
LCM = 5118156680
Thus, we can understand that the LCM of 856,773,221,476,455 is 5118156680.
