Given numbers are 998,400,961,117
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,400,961,117 is 22442425200.
Find LCM of 998,400,961,117 with Prime Factorization
2 | 998, 400, 961, 117 |
499, 200, 961, 117 |
Multiply the prime numbers at the bottom and the left side.
2 x 499 x 200 x 961 x 117 = 22442425200
Therefore, the lowest common multiple of 998,400,961,117 is 22442425200.
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.
998 x 400 x 961 x 117 = 44884850400
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.
998 : 1, 2, 499, 998
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
961 : 1, 31, 961
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,400,961,117, is 1.
Now, the common factors can be found like this.
998:2x 499
400:2x 2x 2x 2x 5x 5
961:31x 31
117:3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 44884850400/(1x2)
LCM = 44884850400/2
LCM = 22442425200
Thus, we can understand that the LCM of 998,400,961,117 is 22442425200.
