Find LCM of 870,315,868,935,740 with Prime Factorization
| 2 | 870, 315, 868, 935, 740 |
| 2 | 435, 315, 434, 935, 370 |
| 3 | 435, 315, 217, 935, 185 |
| 5 | 145, 105, 217, 935, 185 |
| 7 | 29, 21, 217, 187, 37 |
| 29, 3, 31, 187, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 29 x 3 x 31 x 187 x 37 = 7837428060
Therefore, the lowest common multiple of 870,315,868,935,740 is 7837428060.
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.
870 x 315 x 868 x 935 x 740 = 164585989260000
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
935 : 1, 5, 11, 17, 55, 85, 187, 935
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,315,868,935,740, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
315:3x 3x 5x 7
868:2x 2x 7x 31
935:5x 11x 17
740:2x 2x 5x 37
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 7 = 21000
Therefore, the value for common factors is 21000.
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 = 164585989260000/(1x21000)
LCM = 164585989260000/21000
LCM = 7837428060
Thus, we can understand that the LCM of 870,315,868,935,740 is 7837428060.
