Given numbers are 840,340,901,759
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,340,901,759 is 191480520.
Find LCM of 840,340,901,759 with Prime Factorization
| 2 | 840, 340, 901, 759 |
| 2 | 420, 170, 901, 759 |
| 3 | 210, 85, 901, 759 |
| 5 | 70, 85, 901, 253 |
| 17 | 14, 17, 901, 253 |
| 14, 1, 53, 253 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 14 x 1 x 53 x 253 = 191480520
Therefore, the lowest common multiple of 840,340,901,759 is 191480520.
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.
840 x 340 x 901 x 759 = 195310130400
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.
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
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
901 : 1, 17, 53, 901
759 : 1, 3, 11, 23, 33, 69, 253, 759
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,340,901,759, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
340:2x 2x 5x 17
901:17x 53
759:3x 11x 23
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 3x 5x 17 = 1020
Therefore, the value for common factors is 1020.
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 = 195310130400/(1x1020)
LCM = 195310130400/1020
LCM = 191480520
Thus, we can understand that the LCM of 840,340,901,759 is 191480520.
