Given numbers are 759,840,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,840,427 is 12963720.
Find LCM of 759,840,427 with Prime Factorization
| 3 | 759, 840, 427 |
| 7 | 253, 280, 427 |
| 253, 40, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 253 x 40 x 61 = 12963720
Therefore, the lowest common multiple of 759,840,427 is 12963720.
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.
759 x 840 x 427 = 272238120
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
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
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,840,427, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
840:2x 2x 2x 3x 5x 7
427:7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 272238120/(1x21)
LCM = 272238120/21
LCM = 12963720
Thus, we can understand that the LCM of 759,840,427 is 12963720.
