Given numbers are 310,310,266,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,310,266,989 is 40776470.
Find LCM of 310,310,266,989 with Prime Factorization
| 2 | 310, 310, 266, 989 |
| 5 | 155, 155, 133, 989 |
| 31 | 31, 31, 133, 989 |
| 1, 1, 133, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 1 x 1 x 133 x 989 = 40776470
Therefore, the lowest common multiple of 310,310,266,989 is 40776470.
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.
310 x 310 x 266 x 989 = 25281411400
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
310 : 1, 2, 5, 10, 31, 62, 155, 310
266 : 1, 2, 7, 14, 19, 38, 133, 266
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,310,266,989, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
310:2x 5x 31
266:2x 7x 19
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 2x 5x 31 = 620
Therefore, the value for common factors is 620.
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 = 25281411400/(1x620)
LCM = 25281411400/620
LCM = 40776470
Thus, we can understand that the LCM of 310,310,266,989 is 40776470.
