Given numbers are 897,639,649,502,834
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,639,649,502,834 is 8652373543242.
Find LCM of 897,639,649,502,834 with Prime Factorization
| 2 | 897, 639, 649, 502, 834 |
| 3 | 897, 639, 649, 251, 417 |
| 299, 213, 649, 251, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 299 x 213 x 649 x 251 x 139 = 8652373543242
Therefore, the lowest common multiple of 897,639,649,502,834 is 8652373543242.
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.
897 x 639 x 649 x 502 x 834 = 155742723778356
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
639 : 1, 3, 9, 71, 213, 639
649 : 1, 11, 59, 649
502 : 1, 2, 251, 502
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,639,649,502,834, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
639:3x 3x 71
649:11x 59
502:2x 251
834:2x 3x 139
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 3 = 18
Therefore, the value for common factors is 18.
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 = 155742723778356/(1x18)
LCM = 155742723778356/18
LCM = 8652373543242
Thus, we can understand that the LCM of 897,639,649,502,834 is 8652373543242.
