Given numbers are 768,909,812,252
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,909,812,252 is 47238912.
Find LCM of 768,909,812,252 with Prime Factorization
| 2 | 768, 909, 812, 252 |
| 2 | 384, 909, 406, 126 |
| 3 | 192, 909, 203, 63 |
| 3 | 64, 303, 203, 21 |
| 7 | 64, 101, 203, 7 |
| 64, 101, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 64 x 101 x 29 x 1 = 47238912
Therefore, the lowest common multiple of 768,909,812,252 is 47238912.
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 909 x 812 x 252 = 142850469888
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
909 : 1, 3, 9, 101, 303, 909
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,909,812,252, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
909:3x 3x 101
812:2x 2x 7x 29
252:2x 2x 3x 3x 7
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 3x 3x 3x 7 = 3024
Therefore, the value for common factors is 3024.
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 = 142850469888/(1x3024)
LCM = 142850469888/3024
LCM = 47238912
Thus, we can understand that the LCM of 768,909,812,252 is 47238912.
