Given numbers are 297,732,122,991,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,732,122,991,490 is 17594868060.
Find LCM of 297,732,122,991,490 with Prime Factorization
| 2 | 297, 732, 122, 991, 490 |
| 3 | 297, 366, 61, 991, 245 |
| 61 | 99, 122, 61, 991, 245 |
| 99, 2, 1, 991, 245 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 61 x 99 x 2 x 1 x 991 x 245 = 17594868060
Therefore, the lowest common multiple of 297,732,122,991,490 is 17594868060.
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.
297 x 732 x 122 x 991 x 490 = 12879443419920
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
122 : 1, 2, 61, 122
991 : 1, 991
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,732,122,991,490, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
732:2x 2x 3x 61
122:2x 61
991:991
490:2x 5x 7x 7
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 3x 61 = 732
Therefore, the value for common factors is 732.
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 = 12879443419920/(1x732)
LCM = 12879443419920/732
LCM = 17594868060
Thus, we can understand that the LCM of 297,732,122,991,490 is 17594868060.
