Given numbers are 829,921,326,428,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 829,921,326,428,749 is 372858093132.
Find LCM of 829,921,326,428,749 with Prime Factorization
| 2 | 829, 921, 326, 428, 749 |
| 107 | 829, 921, 163, 214, 749 |
| 829, 921, 163, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 829 x 921 x 163 x 2 x 7 = 372858093132
Therefore, the lowest common multiple of 829,921,326,428,749 is 372858093132.
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.
829 x 921 x 326 x 428 x 749 = 79791631930248
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.
829 : 1, 829
921 : 1, 3, 307, 921
326 : 1, 2, 163, 326
428 : 1, 2, 4, 107, 214, 428
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,921,326,428,749, is 1.
Now, the common factors can be found like this.
829:829
921:3x 307
326:2x 163
428:2x 2x 107
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 107 = 214
Therefore, the value for common factors is 214.
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 = 79791631930248/(1x214)
LCM = 79791631930248/214
LCM = 372858093132
Thus, we can understand that the LCM of 829,921,326,428,749 is 372858093132.
