Given numbers are 696,630,986,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 696,630,986,830 is 103115880.
Find LCM of 696,630,986,830 with Prime Factorization
| 2 | 696, 630, 986, 830 |
| 3 | 348, 315, 493, 415 |
| 5 | 116, 105, 493, 415 |
| 29 | 116, 21, 493, 83 |
| 4, 21, 17, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 4 x 21 x 17 x 83 = 103115880
Therefore, the lowest common multiple of 696,630,986,830 is 103115880.
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.
696 x 630 x 986 x 830 = 358843262400
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.
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
986 : 1, 2, 17, 29, 34, 58, 493, 986
830 : 1, 2, 5, 10, 83, 166, 415, 830
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 696,630,986,830, is 2.
Now, the common factors can be found like this.
696:2x 2x 2x 3x 29
630:2x 3x 3x 5x 7
986:2x 17x 29
830:2x 5x 83
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 29 = 1740
Therefore, the value for common factors is 1740.
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 = 358843262400/(2x1740)
LCM = 358843262400/3480
LCM = 103115880
Thus, we can understand that the LCM of 696,630,986,830 is 103115880.
