Given numbers are 665,949,819,637,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,949,819,637,786 is 10416689010.
Find LCM of 665,949,819,637,786 with Prime Factorization
| 3 | 665, 949, 819, 637, 786 |
| 7 | 665, 949, 273, 637, 262 |
| 13 | 95, 949, 39, 91, 262 |
| 95, 73, 3, 7, 262 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 95 x 73 x 3 x 7 x 262 = 10416689010
Therefore, the lowest common multiple of 665,949,819,637,786 is 10416689010.
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.
665 x 949 x 819 x 637 x 786 = 258781805075430
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
949 : 1, 13, 73, 949
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
637 : 1, 7, 13, 49, 91, 637
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,949,819,637,786, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
949:13x 73
819:3x 3x 7x 13
637:7x 7x 13
786:2x 3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 13x 13 = 24843
Therefore, the value for common factors is 24843.
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 = 258781805075430/(1x24843)
LCM = 258781805075430/24843
LCM = 10416689010
Thus, we can understand that the LCM of 665,949,819,637,786 is 10416689010.
