Find LCM of 868,746,945,918,554 with Prime Factorization
| 2 | 868, 746, 945, 918, 554 |
| 3 | 434, 373, 945, 459, 277 |
| 3 | 434, 373, 315, 153, 277 |
| 3 | 434, 373, 105, 51, 277 |
| 7 | 434, 373, 35, 17, 277 |
| 62, 373, 5, 17, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 62 x 373 x 5 x 17 x 277 = 205821631260
Therefore, the lowest common multiple of 868,746,945,918,554 is 205821631260.
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.
868 x 746 x 945 x 918 x 554 = 311202306465120
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
746 : 1, 2, 373, 746
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,746,945,918,554, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
746:2x 373
945:3x 3x 3x 5x 7
918:2x 3x 3x 3x 17
554:2x 277
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 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 311202306465120/(1x1512)
LCM = 311202306465120/1512
LCM = 205821631260
Thus, we can understand that the LCM of 868,746,945,918,554 is 205821631260.
