Given numbers are 990,616,561,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,616,561,393 is 61732440.
Find LCM of 990,616,561,393 with Prime Factorization
2 | 990, 616, 561, 393 |
3 | 495, 308, 561, 393 |
11 | 165, 308, 187, 131 |
15, 28, 17, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 15 x 28 x 17 x 131 = 61732440
Therefore, the lowest common multiple of 990,616,561,393 is 61732440.
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.
990 x 616 x 561 x 393 = 134453254320
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
561 : 1, 3, 11, 17, 33, 51, 187, 561
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,616,561,393, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
616:2x 2x 2x 7x 11
561:3x 11x 17
393:3x 131
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 3x 11x 11 = 2178
Therefore, the value for common factors is 2178.
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 = 134453254320/(1x2178)
LCM = 134453254320/2178
LCM = 61732440
Thus, we can understand that the LCM of 990,616,561,393 is 61732440.
