Given numbers are 851,847,565,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,847,565,161 is 407250305.
Find LCM of 851,847,565,161 with Prime Factorization
| 7 | 851, 847, 565, 161 |
| 23 | 851, 121, 565, 23 |
| 37, 121, 565, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 37 x 121 x 565 x 1 = 407250305
Therefore, the lowest common multiple of 851,847,565,161 is 407250305.
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.
851 x 847 x 565 x 161 = 65567299105
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.
851 : 1, 23, 37, 851
847 : 1, 7, 11, 77, 121, 847
565 : 1, 5, 113, 565
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,847,565,161, is 1.
Now, the common factors can be found like this.
851:23x 37
847:7x 11x 11
565:5x 113
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 65567299105/(1x161)
LCM = 65567299105/161
LCM = 407250305
Thus, we can understand that the LCM of 851,847,565,161 is 407250305.
