Given numbers are 131,622,690,544
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,622,690,544 is 7646270880.
Find LCM of 131,622,690,544 with Prime Factorization
| 2 | 131, 622, 690, 544 |
| 131, 311, 345, 272 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 311 x 345 x 272 = 7646270880
Therefore, the lowest common multiple of 131,622,690,544 is 7646270880.
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.
131 x 622 x 690 x 544 = 30585083520
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.
131 : 1, 131
622 : 1, 2, 311, 622
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,622,690,544, is 1.
Now, the common factors can be found like this.
131:131
622:2x 311
690:2x 3x 5x 23
544:2x 2x 2x 2x 2x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 30585083520/(1x4)
LCM = 30585083520/4
LCM = 7646270880
Thus, we can understand that the LCM of 131,622,690,544 is 7646270880.
