Given numbers are 805,662,690,736,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,662,690,736,645 is 1099926240.
Find LCM of 805,662,690,736,645 with Prime Factorization
| 2 | 805, 662, 690, 736, 645 |
| 3 | 805, 331, 345, 368, 645 |
| 5 | 805, 331, 115, 368, 215 |
| 23 | 161, 331, 23, 368, 43 |
| 7, 331, 1, 16, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 7 x 331 x 1 x 16 x 43 = 1099926240
Therefore, the lowest common multiple of 805,662,690,736,645 is 1099926240.
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.
805 x 662 x 690 x 736 x 645 = 174558294288000
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
662 : 1, 2, 331, 662
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,662,690,736,645, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
662:2x 331
690:2x 3x 5x 23
736:2x 2x 2x 2x 2x 23
645:3x 5x 43
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 5x 5x 23x 23 = 158700
Therefore, the value for common factors is 158700.
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 = 174558294288000/(1x158700)
LCM = 174558294288000/158700
LCM = 1099926240
Thus, we can understand that the LCM of 805,662,690,736,645 is 1099926240.
