Given numbers are 325,649,780,645,949
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 325,649,780,645,949 is 7945122900.
Find LCM of 325,649,780,645,949 with Prime Factorization
| 3 | 325, 649, 780, 645, 949 |
| 5 | 325, 649, 260, 215, 949 |
| 13 | 65, 649, 52, 43, 949 |
| 5, 649, 4, 43, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 5 x 649 x 4 x 43 x 73 = 7945122900
Therefore, the lowest common multiple of 325,649,780,645,949 is 7945122900.
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.
325 x 649 x 780 x 645 x 949 = 100704432757500
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.
325 : 1, 5, 13, 25, 65, 325
649 : 1, 11, 59, 649
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
645 : 1, 3, 5, 15, 43, 129, 215, 645
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 325,649,780,645,949, is 1.
Now, the common factors can be found like this.
325:5x 5x 13
649:11x 59
780:2x 2x 3x 5x 13
645:3x 5x 43
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 13x 13 = 12675
Therefore, the value for common factors is 12675.
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 = 100704432757500/(1x12675)
LCM = 100704432757500/12675
LCM = 7945122900
Thus, we can understand that the LCM of 325,649,780,645,949 is 7945122900.
