Find LCM of 748,835,870,990,900 with Prime Factorization
| 2 | 748, 835, 870, 990, 900 |
| 2 | 374, 835, 435, 495, 450 |
| 3 | 187, 835, 435, 495, 225 |
| 3 | 187, 835, 145, 165, 75 |
| 5 | 187, 835, 145, 55, 25 |
| 11 | 187, 167, 29, 11, 5 |
| 17, 167, 29, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 17 x 167 x 29 x 1 x 5 = 815076900
Therefore, the lowest common multiple of 748,835,870,990,900 is 815076900.
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.
748 x 835 x 870 x 990 x 900 = 484155678600000
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
835 : 1, 5, 167, 835
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,835,870,990,900, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
835:5x 167
870:2x 3x 5x 29
990:2x 3x 3x 5x 11
900:2x 2x 3x 3x 5x 5
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 2x 3x 3x 3x 5x 5x 5x 11 = 594000
Therefore, the value for common factors is 594000.
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 = 484155678600000/(1x594000)
LCM = 484155678600000/594000
LCM = 815076900
Thus, we can understand that the LCM of 748,835,870,990,900 is 815076900.
