Given numbers are 149,868,802,512,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 149,868,802,512,121 is 803240700416.
Find LCM of 149,868,802,512,121 with Prime Factorization
| 2 | 149, 868, 802, 512, 121 |
| 2 | 149, 434, 401, 256, 121 |
| 149, 217, 401, 128, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 149 x 217 x 401 x 128 x 121 = 803240700416
Therefore, the lowest common multiple of 149,868,802,512,121 is 803240700416.
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.
149 x 868 x 802 x 512 x 121 = 6425925603328
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.
149 : 1, 149
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
802 : 1, 2, 401, 802
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 149,868,802,512,121, is 1.
Now, the common factors can be found like this.
149:149
868:2x 2x 7x 31
802:2x 401
512:2x 2x 2x 2x 2x 2x 2x 2x 2
121:11x 11
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 2 = 8
Therefore, the value for common factors is 8.
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 = 6425925603328/(1x8)
LCM = 6425925603328/8
LCM = 803240700416
Thus, we can understand that the LCM of 149,868,802,512,121 is 803240700416.
