Given numbers are 647,981,177,531,699
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,981,177,531,699 is 8725317129.
Find LCM of 647,981,177,531,699 with Prime Factorization
| 3 | 647, 981, 177, 531, 699 |
| 3 | 647, 327, 59, 177, 233 |
| 59 | 647, 109, 59, 59, 233 |
| 647, 109, 1, 1, 233 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 59 x 647 x 109 x 1 x 1 x 233 = 8725317129
Therefore, the lowest common multiple of 647,981,177,531,699 is 8725317129.
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.
647 x 981 x 177 x 531 x 699 = 41698290559491
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.
647 : 1, 647
981 : 1, 3, 9, 109, 327, 981
177 : 1, 3, 59, 177
531 : 1, 3, 9, 59, 177, 531
699 : 1, 3, 233, 699
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,981,177,531,699, is 1.
Now, the common factors can be found like this.
647:647
981:3x 3x 109
177:3x 59
531:3x 3x 59
699:3x 233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 59 = 4779
Therefore, the value for common factors is 4779.
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 = 41698290559491/(1x4779)
LCM = 41698290559491/4779
LCM = 8725317129
Thus, we can understand that the LCM of 647,981,177,531,699 is 8725317129.
