Given numbers are 921,450,979,534
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,450,979,534 is 135248850.
Find LCM of 921,450,979,534 with Prime Factorization
| 2 | 921, 450, 979, 534 |
| 3 | 921, 225, 979, 267 |
| 89 | 307, 75, 979, 89 |
| 307, 75, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 89 x 307 x 75 x 11 x 1 = 135248850
Therefore, the lowest common multiple of 921,450,979,534 is 135248850.
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 450 x 979 x 534 = 216668657700
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
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
979 : 1, 11, 89, 979
534 : 1, 2, 3, 6, 89, 178, 267, 534
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,450,979,534, is 1.
Now, the common factors can be found like this.
921:3x 307
450:2x 3x 3x 5x 5
979:11x 89
534:2x 3x 89
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 89 = 1602
Therefore, the value for common factors is 1602.
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 = 216668657700/(1x1602)
LCM = 216668657700/1602
LCM = 135248850
Thus, we can understand that the LCM of 921,450,979,534 is 135248850.
