Given numbers are 957,621,650,874,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,621,650,874,989 is 105200473950.
Find LCM of 957,621,650,874,989 with Prime Factorization
| 2 | 957, 621, 650, 874, 989 |
| 3 | 957, 621, 325, 437, 989 |
| 23 | 319, 207, 325, 437, 989 |
| 319, 9, 325, 19, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 319 x 9 x 325 x 19 x 43 = 105200473950
Therefore, the lowest common multiple of 957,621,650,874,989 is 105200473950.
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.
957 x 621 x 650 x 874 x 989 = 333906304317300
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
621 : 1, 3, 9, 23, 27, 69, 207, 621
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
874 : 1, 2, 19, 23, 38, 46, 437, 874
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,621,650,874,989, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
621:3x 3x 3x 23
650:2x 5x 5x 13
874:2x 19x 23
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23x 23 = 3174
Therefore, the value for common factors is 3174.
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 = 333906304317300/(1x3174)
LCM = 333906304317300/3174
LCM = 105200473950
Thus, we can understand that the LCM of 957,621,650,874,989 is 105200473950.
