Find LCM of 924,841,660,647 with Prime Factorization
| 2 | 924, 841, 660, 647 |
| 2 | 462, 841, 330, 647 |
| 3 | 231, 841, 165, 647 |
| 11 | 77, 841, 55, 647 |
| 7, 841, 5, 647 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 7 x 841 x 5 x 647 = 2513866740
Therefore, the lowest common multiple of 924,841,660,647 is 2513866740.
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.
924 x 841 x 660 x 647 = 331830409680
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.
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
841 : 1, 29, 841
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,841,660,647, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
841:29x 29
660:2x 2x 3x 5x 11
647:647
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 331830409680/(1x132)
LCM = 331830409680/132
LCM = 2513866740
Thus, we can understand that the LCM of 924,841,660,647 is 2513866740.
