Given numbers are 833,392,691,497
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 833,392,691,497 is 326942504.
Find LCM of 833,392,691,497 with Prime Factorization
| 7 | 833, 392, 691, 497 |
| 7 | 119, 56, 691, 71 |
| 17, 8, 691, 71 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 17 x 8 x 691 x 71 = 326942504
Therefore, the lowest common multiple of 833,392,691,497 is 326942504.
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.
833 x 392 x 691 x 497 = 112141278872
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.
833 : 1, 7, 17, 49, 119, 833
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
691 : 1, 691
497 : 1, 7, 71, 497
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,392,691,497, is 1.
Now, the common factors can be found like this.
833:7x 7x 17
392:2x 2x 2x 7x 7
691:691
497:7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 7 = 343
Therefore, the value for common factors is 343.
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 = 112141278872/(1x343)
LCM = 112141278872/343
LCM = 326942504
Thus, we can understand that the LCM of 833,392,691,497 is 326942504.
