Find LCM of 910,650,455,918,840 with Prime Factorization
| 2 | 910, 650, 455, 918, 840 |
| 3 | 455, 325, 455, 459, 420 |
| 5 | 455, 325, 455, 153, 140 |
| 7 | 91, 65, 91, 153, 28 |
| 13 | 13, 65, 13, 153, 4 |
| 1, 5, 1, 153, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 1 x 5 x 1 x 153 x 4 = 8353800
Therefore, the lowest common multiple of 910,650,455,918,840 is 8353800.
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.
910 x 650 x 455 x 918 x 840 = 207533453400000
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
455 : 1, 5, 7, 13, 35, 65, 91, 455
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,650,455,918,840, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
650:2x 5x 5x 13
455:5x 7x 13
918:2x 3x 3x 3x 17
840:2x 2x 2x 3x 5x 7
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 2x 3x 5x 5x 5x 7x 7x 13x 13 = 24843000
Therefore, the value for common factors is 24843000.
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 = 207533453400000/(1x24843000)
LCM = 207533453400000/24843000
LCM = 8353800
Thus, we can understand that the LCM of 910,650,455,918,840 is 8353800.
