Given numbers are 759,840,931,792
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,840,931,792 is 84795480.
Find LCM of 759,840,931,792 with Prime Factorization
| 2 | 759, 840, 931, 792 |
| 2 | 759, 420, 931, 396 |
| 2 | 759, 210, 931, 198 |
| 3 | 759, 105, 931, 99 |
| 7 | 253, 35, 931, 33 |
| 11 | 253, 5, 133, 33 |
| 23, 5, 133, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 23 x 5 x 133 x 3 = 84795480
Therefore, the lowest common multiple of 759,840,931,792 is 84795480.
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 931 x 792 = 470106141120
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
931 : 1, 7, 19, 49, 133, 931
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,840,931,792, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
840:2x 2x 2x 3x 5x 7
931:7x 7x 19
792:2x 2x 2x 3x 3x 11
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 7x 11 = 5544
Therefore, the value for common factors is 5544.
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 = 470106141120/(1x5544)
LCM = 470106141120/5544
LCM = 84795480
Thus, we can understand that the LCM of 759,840,931,792 is 84795480.
