Find LCM of 924,645,645,556,772 with Prime Factorization
| 2 | 924, 645, 645, 556, 772 |
| 2 | 462, 645, 645, 278, 386 |
| 3 | 231, 645, 645, 139, 193 |
| 5 | 77, 215, 215, 139, 193 |
| 43 | 77, 43, 43, 139, 193 |
| 77, 1, 1, 139, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 77 x 1 x 1 x 139 x 193 = 5329451820
Therefore, the lowest common multiple of 924,645,645,556,772 is 5329451820.
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 645 x 645 x 556 x 772 = 164999828347200
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
645 : 1, 3, 5, 15, 43, 129, 215, 645
645 : 1, 3, 5, 15, 43, 129, 215, 645
556 : 1, 2, 4, 139, 278, 556
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,645,645,556,772, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
645:3x 5x 43
645:3x 5x 43
556:2x 2x 139
772:2x 2x 193
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 3x 3x 5x 43 = 30960
Therefore, the value for common factors is 30960.
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 = 164999828347200/(1x30960)
LCM = 164999828347200/30960
LCM = 5329451820
Thus, we can understand that the LCM of 924,645,645,556,772 is 5329451820.
