Given numbers are 682,445,730,695,973
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,445,730,695,973 is 21556591210.
Find LCM of 682,445,730,695,973 with Prime Factorization
| 2 | 682, 445, 730, 695, 973 |
| 5 | 341, 445, 365, 695, 973 |
| 139 | 341, 89, 73, 139, 973 |
| 341, 89, 73, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 139 x 341 x 89 x 73 x 1 x 7 = 21556591210
Therefore, the lowest common multiple of 682,445,730,695,973 is 21556591210.
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.
682 x 445 x 730 x 695 x 973 = 149818308909500
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
445 : 1, 5, 89, 445
730 : 1, 2, 5, 10, 73, 146, 365, 730
695 : 1, 5, 139, 695
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,445,730,695,973, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
445:5x 89
730:2x 5x 73
695:5x 139
973:7x 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 5x 5x 139 = 6950
Therefore, the value for common factors is 6950.
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 = 149818308909500/(1x6950)
LCM = 149818308909500/6950
LCM = 21556591210
Thus, we can understand that the LCM of 682,445,730,695,973 is 21556591210.
