Given numbers are 957,343,980,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,343,980,987 is 308555940.
Find LCM of 957,343,980,987 with Prime Factorization
| 3 | 957, 343, 980, 987 |
| 7 | 319, 343, 980, 329 |
| 7 | 319, 49, 140, 47 |
| 319, 7, 20, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 7 x 319 x 7 x 20 x 47 = 308555940
Therefore, the lowest common multiple of 957,343,980,987 is 308555940.
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 343 x 980 x 987 = 317504062260
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
343 : 1, 7, 49, 343
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,343,980,987, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
343:7x 7x 7
980:2x 2x 5x 7x 7
987:3x 7x 47
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 7 = 1029
Therefore, the value for common factors is 1029.
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 = 317504062260/(1x1029)
LCM = 317504062260/1029
LCM = 308555940
Thus, we can understand that the LCM of 957,343,980,987 is 308555940.
