Given numbers are 969,781,260,765,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,781,260,765,805 is 95037562620.
Find LCM of 969,781,260,765,805 with Prime Factorization
| 3 | 969, 781, 260, 765, 805 |
| 5 | 323, 781, 260, 255, 805 |
| 17 | 323, 781, 52, 51, 161 |
| 19, 781, 52, 3, 161 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 19 x 781 x 52 x 3 x 161 = 95037562620
Therefore, the lowest common multiple of 969,781,260,765,805 is 95037562620.
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.
969 x 781 x 260 x 765 x 805 = 121172892340500
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
781 : 1, 11, 71, 781
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,781,260,765,805, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
781:11x 71
260:2x 2x 5x 13
765:3x 3x 5x 17
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 17 = 1275
Therefore, the value for common factors is 1275.
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 = 121172892340500/(1x1275)
LCM = 121172892340500/1275
LCM = 95037562620
Thus, we can understand that the LCM of 969,781,260,765,805 is 95037562620.
