Given numbers are 989,717,474,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,717,474,102 is 1904677518.
Find LCM of 989,717,474,102 with Prime Factorization
| 2 | 989, 717, 474, 102 |
| 3 | 989, 717, 237, 51 |
| 989, 239, 79, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 989 x 239 x 79 x 17 = 1904677518
Therefore, the lowest common multiple of 989,717,474,102 is 1904677518.
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.
989 x 717 x 474 x 102 = 34284195324
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.
989 : 1, 23, 43, 989
717 : 1, 3, 239, 717
474 : 1, 2, 3, 6, 79, 158, 237, 474
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,717,474,102, is 1.
Now, the common factors can be found like this.
989:23x 43
717:3x 239
474:2x 3x 79
102:2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 34284195324/(1x18)
LCM = 34284195324/18
LCM = 1904677518
Thus, we can understand that the LCM of 989,717,474,102 is 1904677518.
