Given numbers are 768,769,696,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,769,696,748 is 3202780416.
Find LCM of 768,769,696,748 with Prime Factorization
| 2 | 768, 769, 696, 748 |
| 2 | 384, 769, 348, 374 |
| 2 | 192, 769, 174, 187 |
| 3 | 96, 769, 87, 187 |
| 32, 769, 29, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 32 x 769 x 29 x 187 = 3202780416
Therefore, the lowest common multiple of 768,769,696,748 is 3202780416.
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.
768 x 769 x 696 x 748 = 307466919936
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
769 : 1, 769
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,769,696,748, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
769:769
696:2x 2x 2x 3x 29
748:2x 2x 11x 17
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 3 = 96
Therefore, the value for common factors is 96.
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 = 307466919936/(1x96)
LCM = 307466919936/96
LCM = 3202780416
Thus, we can understand that the LCM of 768,769,696,748 is 3202780416.
