Find LCM of 947,208,145,464,868 with Prime Factorization
| 2 | 947, 208, 145, 464, 868 |
| 2 | 947, 104, 145, 232, 434 |
| 2 | 947, 52, 145, 116, 217 |
| 2 | 947, 26, 145, 58, 217 |
| 29 | 947, 13, 145, 29, 217 |
| 947, 13, 5, 1, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 29 x 947 x 13 x 5 x 1 x 217 = 6197849840
Therefore, the lowest common multiple of 947,208,145,464,868 is 6197849840.
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.
947 x 208 x 145 x 464 x 868 = 11503209303040
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.
947 : 1, 947
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
145 : 1, 5, 29, 145
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,208,145,464,868, is 1.
Now, the common factors can be found like this.
947:947
208:2x 2x 2x 2x 13
145:5x 29
464:2x 2x 2x 2x 29
868:2x 2x 7x 31
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 2x 29 = 1856
Therefore, the value for common factors is 1856.
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 = 11503209303040/(1x1856)
LCM = 11503209303040/1856
LCM = 6197849840
Thus, we can understand that the LCM of 947,208,145,464,868 is 6197849840.
