Given numbers are 721,530,103,684,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,530,103,684,849 is 36984834180.
Find LCM of 721,530,103,684,849 with Prime Factorization
| 2 | 721, 530, 103, 684, 849 |
| 3 | 721, 265, 103, 342, 849 |
| 103 | 721, 265, 103, 114, 283 |
| 7, 265, 1, 114, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 7 x 265 x 1 x 114 x 283 = 36984834180
Therefore, the lowest common multiple of 721,530,103,684,849 is 36984834180.
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.
721 x 530 x 103 x 684 x 849 = 22856627523240
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.
721 : 1, 7, 103, 721
530 : 1, 2, 5, 10, 53, 106, 265, 530
103 : 1, 103
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,530,103,684,849, is 1.
Now, the common factors can be found like this.
721:7x 103
530:2x 5x 53
103:103
684:2x 2x 3x 3x 19
849:3x 283
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 103 = 618
Therefore, the value for common factors is 618.
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 = 22856627523240/(1x618)
LCM = 22856627523240/618
LCM = 36984834180
Thus, we can understand that the LCM of 721,530,103,684,849 is 36984834180.
