Given numbers are 997,637,779,665,887
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 997,637,779,665,887 is 2194146757985.
Find LCM of 997,637,779,665,887 with Prime Factorization
| 7 | 997, 637, 779, 665, 887 |
| 19 | 997, 91, 779, 95, 887 |
| 997, 91, 41, 5, 887 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 997 x 91 x 41 x 5 x 887 = 2194146757985
Therefore, the lowest common multiple of 997,637,779,665,887 is 2194146757985.
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.
997 x 637 x 779 x 665 x 887 = 291821518812005
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.
997 : 1, 997
637 : 1, 7, 13, 49, 91, 637
779 : 1, 19, 41, 779
665 : 1, 5, 7, 19, 35, 95, 133, 665
887 : 1, 887
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,637,779,665,887, is 1.
Now, the common factors can be found like this.
997:997
637:7x 7x 13
779:19x 41
665:5x 7x 19
887:887
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 291821518812005/(1x133)
LCM = 291821518812005/133
LCM = 2194146757985
Thus, we can understand that the LCM of 997,637,779,665,887 is 2194146757985.
