Given numbers are 131,456,836,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,456,836,370 is 121562760.
Find LCM of 131,456,836,370 with Prime Factorization
| 2 | 131, 456, 836, 370 |
| 2 | 131, 228, 418, 185 |
| 19 | 131, 114, 209, 185 |
| 131, 6, 11, 185 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 131 x 6 x 11 x 185 = 121562760
Therefore, the lowest common multiple of 131,456,836,370 is 121562760.
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 456 x 836 x 370 = 18477539520
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
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,456,836,370, is 1.
Now, the common factors can be found like this.
131:131
456:2x 2x 2x 3x 19
836:2x 2x 11x 19
370:2x 5x 37
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 19 = 152
Therefore, the value for common factors is 152.
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 = 18477539520/(1x152)
LCM = 18477539520/152
LCM = 121562760
Thus, we can understand that the LCM of 131,456,836,370 is 121562760.
