Given numbers are 301,961,405,989,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 301,961,405,989,644 is 10777864860.
Find LCM of 301,961,405,989,644 with Prime Factorization
| 7 | 301, 961, 405, 989, 644 |
| 23 | 43, 961, 405, 989, 92 |
| 43 | 43, 961, 405, 43, 4 |
| 1, 961, 405, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 43 x 1 x 961 x 405 x 1 x 4 = 10777864860
Therefore, the lowest common multiple of 301,961,405,989,644 is 10777864860.
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.
301 x 961 x 405 x 989 x 644 = 74615158425780
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.
301 : 1, 7, 43, 301
961 : 1, 31, 961
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
989 : 1, 23, 43, 989
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 301,961,405,989,644, is 1.
Now, the common factors can be found like this.
301:7x 43
961:31x 31
405:3x 3x 3x 3x 5
989:23x 43
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23x 43 = 6923
Therefore, the value for common factors is 6923.
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 = 74615158425780/(1x6923)
LCM = 74615158425780/6923
LCM = 10777864860
Thus, we can understand that the LCM of 301,961,405,989,644 is 10777864860.
