Given numbers are 198,768,946,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,768,946,556 is 151481088.
Find LCM of 198,768,946,556 with Prime Factorization
2 | 198, 768, 946, 556 |
2 | 99, 384, 473, 278 |
3 | 99, 192, 473, 139 |
11 | 33, 64, 473, 139 |
3, 64, 43, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 3 x 64 x 43 x 139 = 151481088
Therefore, the lowest common multiple of 198,768,946,556 is 151481088.
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.
198 x 768 x 946 x 556 = 79982014464
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
946 : 1, 2, 11, 22, 43, 86, 473, 946
556 : 1, 2, 4, 139, 278, 556
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,768,946,556, is 2.
Now, the common factors can be found like this.
198:2x 3x 3x 11
768:2x 2x 2x 2x 2x 2x 2x 2x 3
946:2x 11x 43
556:2x 2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 79982014464/(2x264)
LCM = 79982014464/528
LCM = 151481088
Thus, we can understand that the LCM of 198,768,946,556 is 151481088.
