Given numbers are 970,190,905,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 970,190,905,905 is 3335830.
Find LCM of 970,190,905,905 with Prime Factorization
| 2 | 970, 190, 905, 905 |
| 5 | 485, 95, 905, 905 |
| 181 | 97, 19, 181, 181 |
| 97, 19, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 181 x 97 x 19 x 1 x 1 = 3335830
Therefore, the lowest common multiple of 970,190,905,905 is 3335830.
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.
970 x 190 x 905 x 905 = 150946307500
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
190 : 1, 2, 5, 10, 19, 38, 95, 190
905 : 1, 5, 181, 905
905 : 1, 5, 181, 905
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,190,905,905, is 5.
Now, the common factors can be found like this.
970:2x 5x 97
190:2x 5x 19
905:5x 181
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 181 = 9050
Therefore, the value for common factors is 9050.
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 = 150946307500/(5x9050)
LCM = 150946307500/45250
LCM = 3335830
Thus, we can understand that the LCM of 970,190,905,905 is 3335830.
