Find LCM of 798,911,540,228,840 with Prime Factorization
| 2 | 798, 911, 540, 228, 840 |
| 2 | 399, 911, 270, 114, 420 |
| 3 | 399, 911, 135, 57, 210 |
| 5 | 133, 911, 45, 19, 70 |
| 7 | 133, 911, 9, 19, 14 |
| 19 | 19, 911, 9, 19, 2 |
| 1, 911, 9, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 19 x 1 x 911 x 9 x 1 x 2 = 130856040
Therefore, the lowest common multiple of 798,911,540,228,840 is 130856040.
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.
798 x 911 x 540 x 228 x 840 = 75184646342400
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
911 : 1, 911
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
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,911,540,228,840, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
911:911
540:2x 2x 3x 3x 3x 5
228:2x 2x 3x 19
840:2x 2x 2x 3x 5x 7
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 2x 3x 3x 3x 5x 7x 19 = 574560
Therefore, the value for common factors is 574560.
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 = 75184646342400/(1x574560)
LCM = 75184646342400/574560
LCM = 130856040
Thus, we can understand that the LCM of 798,911,540,228,840 is 130856040.
