Given numbers are 773,371,805,621,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 773,371,805,621,920 is 7123689720.
Find LCM of 773,371,805,621,920 with Prime Factorization
| 5 | 773, 371, 805, 621, 920 |
| 7 | 773, 371, 161, 621, 184 |
| 23 | 773, 53, 23, 621, 184 |
| 773, 53, 1, 27, 8 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 773 x 53 x 1 x 27 x 8 = 7123689720
Therefore, the lowest common multiple of 773,371,805,621,920 is 7123689720.
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.
773 x 371 x 805 x 621 x 920 = 131895115165800
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.
773 : 1, 773
371 : 1, 7, 53, 371
805 : 1, 5, 7, 23, 35, 115, 161, 805
621 : 1, 3, 9, 23, 27, 69, 207, 621
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 773,371,805,621,920, is 1.
Now, the common factors can be found like this.
773:773
371:7x 53
805:5x 7x 23
621:3x 3x 3x 23
920:2x 2x 2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 23x 23 = 18515
Therefore, the value for common factors is 18515.
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 = 131895115165800/(1x18515)
LCM = 131895115165800/18515
LCM = 7123689720
Thus, we can understand that the LCM of 773,371,805,621,920 is 7123689720.
