Find LCM of 168,918,901,540 with Prime Factorization
| 2 | 168, 918, 901, 540 |
| 2 | 84, 459, 901, 270 |
| 3 | 42, 459, 901, 135 |
| 3 | 14, 153, 901, 45 |
| 3 | 14, 51, 901, 15 |
| 17 | 14, 17, 901, 5 |
| 14, 1, 53, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 17 x 14 x 1 x 53 x 5 = 6811560
Therefore, the lowest common multiple of 168,918,901,540 is 6811560.
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.
168 x 918 x 901 x 540 = 75036144960
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
901 : 1, 17, 53, 901
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,918,901,540, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
918:2x 3x 3x 3x 17
901:17x 53
540:2x 2x 3x 3x 3x 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 3x 3x 3x 3x 17 = 11016
Therefore, the value for common factors is 11016.
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 = 75036144960/(1x11016)
LCM = 75036144960/11016
LCM = 6811560
Thus, we can understand that the LCM of 168,918,901,540 is 6811560.
