Given numbers are 805,787,189,533,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,787,189,533,905 is 1650213595485.
Find LCM of 805,787,189,533,905 with Prime Factorization
| 5 | 805, 787, 189, 533, 905 |
| 7 | 161, 787, 189, 533, 181 |
| 23, 787, 27, 533, 181 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 787 x 27 x 533 x 181 = 1650213595485
Therefore, the lowest common multiple of 805,787,189,533,905 is 1650213595485.
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 787 x 189 x 533 x 905 = 57757475841975
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
787 : 1, 787
189 : 1, 3, 7, 9, 21, 27, 63, 189
533 : 1, 13, 41, 533
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,787,189,533,905, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
787:787
189:3x 3x 3x 7
533:13x 41
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 57757475841975/(1x35)
LCM = 57757475841975/35
LCM = 1650213595485
Thus, we can understand that the LCM of 805,787,189,533,905 is 1650213595485.
