Given numbers are 7,785,847,795
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,785,847,795 is 105718305.
Find LCM of 7,785,847,795 with Prime Factorization
| 5 | 7, 785, 847, 795 |
| 7 | 7, 157, 847, 159 |
| 1, 157, 121, 159 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 1 x 157 x 121 x 159 = 105718305
Therefore, the lowest common multiple of 7,785,847,795 is 105718305.
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 785 x 847 x 795 = 3700140675
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
785 : 1, 5, 157, 785
847 : 1, 7, 11, 77, 121, 847
795 : 1, 3, 5, 15, 53, 159, 265, 795
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,785,847,795, is 1.
Now, the common factors can be found like this.
7:7
785:5x 157
847:7x 11x 11
795:3x 5x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 3700140675/(1x35)
LCM = 3700140675/35
LCM = 105718305
Thus, we can understand that the LCM of 7,785,847,795 is 105718305.
