Find LCM of 855,646,908,220,564 with Prime Factorization
| 2 | 855, 646, 908, 220, 564 |
| 2 | 855, 323, 454, 110, 282 |
| 3 | 855, 323, 227, 55, 141 |
| 5 | 285, 323, 227, 55, 47 |
| 19 | 57, 323, 227, 11, 47 |
| 3, 17, 227, 11, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 3 x 17 x 227 x 11 x 47 = 6823252260
Therefore, the lowest common multiple of 855,646,908,220,564 is 6823252260.
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.
855 x 646 x 908 x 220 x 564 = 62228060611200
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
646 : 1, 2, 17, 19, 34, 38, 323, 646
908 : 1, 2, 4, 227, 454, 908
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,646,908,220,564, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
646:2x 17x 19
908:2x 2x 227
220:2x 2x 5x 11
564:2x 2x 3x 47
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 2x 2x 3x 5x 19 = 9120
Therefore, the value for common factors is 9120.
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 = 62228060611200/(1x9120)
LCM = 62228060611200/9120
LCM = 6823252260
Thus, we can understand that the LCM of 855,646,908,220,564 is 6823252260.
