Find LCM of 724,456,835,870,911 with Prime Factorization
| 2 | 724, 456, 835, 870, 911 |
| 2 | 362, 228, 835, 435, 911 |
| 3 | 181, 114, 835, 435, 911 |
| 5 | 181, 38, 835, 145, 911 |
| 181, 38, 167, 29, 911 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 181 x 38 x 167 x 29 x 911 = 1820733017640
Therefore, the lowest common multiple of 724,456,835,870,911 is 1820733017640.
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.
724 x 456 x 835 x 870 x 911 = 218487962116800
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.
724 : 1, 2, 4, 181, 362, 724
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
835 : 1, 5, 167, 835
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,456,835,870,911, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
456:2x 2x 2x 3x 19
835:5x 167
870:2x 3x 5x 29
911:911
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 5 = 120
Therefore, the value for common factors is 120.
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 = 218487962116800/(1x120)
LCM = 218487962116800/120
LCM = 1820733017640
Thus, we can understand that the LCM of 724,456,835,870,911 is 1820733017640.
