Given numbers are 162,807,473,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 162,807,473,989 is 474085062.
Find LCM of 162,807,473,989 with Prime Factorization
| 3 | 162, 807, 473, 989 |
| 43 | 54, 269, 473, 989 |
| 54, 269, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 54 x 269 x 11 x 23 = 474085062
Therefore, the lowest common multiple of 162,807,473,989 is 474085062.
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.
162 x 807 x 473 x 989 = 61156972998
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
807 : 1, 3, 269, 807
473 : 1, 11, 43, 473
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,807,473,989, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
807:3x 269
473:11x 43
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 61156972998/(1x129)
LCM = 61156972998/129
LCM = 474085062
Thus, we can understand that the LCM of 162,807,473,989 is 474085062.
