Given numbers are 7,489,807,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,489,807,695 is 639946965.
Find LCM of 7,489,807,695 with Prime Factorization
| 3 | 7, 489, 807, 695 |
| 7, 163, 269, 695 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 163 x 269 x 695 = 639946965
Therefore, the lowest common multiple of 7,489,807,695 is 639946965.
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.
7 x 489 x 807 x 695 = 1919840895
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.
7 : 1, 7
489 : 1, 3, 163, 489
807 : 1, 3, 269, 807
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,489,807,695, is 1.
Now, the common factors can be found like this.
7:7
489:3x 163
807:3x 269
695:5x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 1919840895/(1x3)
LCM = 1919840895/3
LCM = 639946965
Thus, we can understand that the LCM of 7,489,807,695 is 639946965.
