Given numbers are 939,957,621,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,957,621,666 is 4588369038.
Find LCM of 939,957,621,666 with Prime Factorization
| 3 | 939, 957, 621, 666 |
| 3 | 313, 319, 207, 222 |
| 313, 319, 69, 74 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 313 x 319 x 69 x 74 = 4588369038
Therefore, the lowest common multiple of 939,957,621,666 is 4588369038.
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.
939 x 957 x 621 x 666 = 371657892078
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.
939 : 1, 3, 313, 939
957 : 1, 3, 11, 29, 33, 87, 319, 957
621 : 1, 3, 9, 23, 27, 69, 207, 621
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,957,621,666, is 3.
Now, the common factors can be found like this.
939:3x 313
957:3x 11x 29
621:3x 3x 3x 23
666:2x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 371657892078/(3x27)
LCM = 371657892078/81
LCM = 4588369038
Thus, we can understand that the LCM of 939,957,621,666 is 4588369038.
