Find LCM of 765,909,772,442,743 with Prime Factorization
| 2 | 765, 909, 772, 442, 743 |
| 3 | 765, 909, 386, 221, 743 |
| 3 | 255, 303, 386, 221, 743 |
| 17 | 85, 101, 386, 221, 743 |
| 5, 101, 386, 13, 743 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 5 x 101 x 386 x 13 x 743 = 576145634220
Therefore, the lowest common multiple of 765,909,772,442,743 is 576145634220.
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.
765 x 909 x 772 x 442 x 743 = 176300564071320
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
909 : 1, 3, 9, 101, 303, 909
772 : 1, 2, 4, 193, 386, 772
442 : 1, 2, 13, 17, 26, 34, 221, 442
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,909,772,442,743, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
909:3x 3x 101
772:2x 2x 193
442:2x 13x 17
743:743
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 17 = 306
Therefore, the value for common factors is 306.
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 = 176300564071320/(1x306)
LCM = 176300564071320/306
LCM = 576145634220
Thus, we can understand that the LCM of 765,909,772,442,743 is 576145634220.
