Given numbers are 921,754,724,954
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,754,724,954 is 39970232172.
Find LCM of 921,754,724,954 with Prime Factorization
| 2 | 921, 754, 724, 954 |
| 3 | 921, 377, 362, 477 |
| 307, 377, 362, 159 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 377 x 362 x 159 = 39970232172
Therefore, the lowest common multiple of 921,754,724,954 is 39970232172.
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.
921 x 754 x 724 x 954 = 479642786064
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.
921 : 1, 3, 307, 921
754 : 1, 2, 13, 26, 29, 58, 377, 754
724 : 1, 2, 4, 181, 362, 724
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,754,724,954, is 1.
Now, the common factors can be found like this.
921:3x 307
754:2x 13x 29
724:2x 2x 181
954:2x 3x 3x 53
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 3 = 12
Therefore, the value for common factors is 12.
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 = 479642786064/(1x12)
LCM = 479642786064/12
LCM = 39970232172
Thus, we can understand that the LCM of 921,754,724,954 is 39970232172.
