Given numbers are 161,847,814,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,847,814,703 is 27390286.
Find LCM of 161,847,814,703 with Prime Factorization
| 7 | 161, 847, 814, 703 |
| 11 | 23, 121, 814, 703 |
| 37 | 23, 11, 74, 703 |
| 23, 11, 2, 19 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 37 x 23 x 11 x 2 x 19 = 27390286
Therefore, the lowest common multiple of 161,847,814,703 is 27390286.
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.
161 x 847 x 814 x 703 = 78034924814
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.
161 : 1, 7, 23, 161
847 : 1, 7, 11, 77, 121, 847
814 : 1, 2, 11, 22, 37, 74, 407, 814
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,847,814,703, is 1.
Now, the common factors can be found like this.
161:7x 23
847:7x 11x 11
814:2x 11x 37
703:19x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 37 = 2849
Therefore, the value for common factors is 2849.
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 = 78034924814/(1x2849)
LCM = 78034924814/2849
LCM = 27390286
Thus, we can understand that the LCM of 161,847,814,703 is 27390286.
