Given numbers are 771,462,690,264
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,462,690,264 is 54617640.
Find LCM of 771,462,690,264 with Prime Factorization
| 2 | 771, 462, 690, 264 |
| 3 | 771, 231, 345, 132 |
| 11 | 257, 77, 115, 44 |
| 257, 7, 115, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 257 x 7 x 115 x 4 = 54617640
Therefore, the lowest common multiple of 771,462,690,264 is 54617640.
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.
771 x 462 x 690 x 264 = 64885756320
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.
771 : 1, 3, 257, 771
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,462,690,264, is 3.
Now, the common factors can be found like this.
771:3x 257
462:2x 3x 7x 11
690:2x 3x 5x 23
264:2x 2x 2x 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 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 64885756320/(3x396)
LCM = 64885756320/1188
LCM = 54617640
Thus, we can understand that the LCM of 771,462,690,264 is 54617640.
