Given numbers are 981,738,163,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,738,163,107 is 1402988922.
Find LCM of 981,738,163,107 with Prime Factorization
| 3 | 981, 738, 163, 107 |
| 3 | 327, 246, 163, 107 |
| 109, 82, 163, 107 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 109 x 82 x 163 x 107 = 1402988922
Therefore, the lowest common multiple of 981,738,163,107 is 1402988922.
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.
981 x 738 x 163 x 107 = 12626900298
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.
981 : 1, 3, 9, 109, 327, 981
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
163 : 1, 163
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,738,163,107, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
738:2x 3x 3x 41
163:163
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 12626900298/(1x9)
LCM = 12626900298/9
LCM = 1402988922
Thus, we can understand that the LCM of 981,738,163,107 is 1402988922.
