Given numbers are 771,954,912,253,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,954,912,253,451 is 386571171888.
Find LCM of 771,954,912,253,451 with Prime Factorization
| 2 | 771, 954, 912, 253, 451 |
| 3 | 771, 477, 456, 253, 451 |
| 11 | 257, 159, 152, 253, 451 |
| 257, 159, 152, 23, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 257 x 159 x 152 x 23 x 41 = 386571171888
Therefore, the lowest common multiple of 771,954,912,253,451 is 386571171888.
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 954 x 912 x 253 x 451 = 76541092033824
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
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
253 : 1, 11, 23, 253
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,954,912,253,451, is 1.
Now, the common factors can be found like this.
771:3x 257
954:2x 3x 3x 53
912:2x 2x 2x 2x 3x 19
253:11x 23
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 76541092033824/(1x198)
LCM = 76541092033824/198
LCM = 386571171888
Thus, we can understand that the LCM of 771,954,912,253,451 is 386571171888.
