Given numbers are 265,840,156,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 265,840,156,836 is 120960840.
Find LCM of 265,840,156,836 with Prime Factorization
| 2 | 265, 840, 156, 836 |
| 2 | 265, 420, 78, 418 |
| 3 | 265, 210, 39, 209 |
| 5 | 265, 70, 13, 209 |
| 53, 14, 13, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 53 x 14 x 13 x 209 = 120960840
Therefore, the lowest common multiple of 265,840,156,836 is 120960840.
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.
265 x 840 x 156 x 836 = 29030601600
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.
265 : 1, 5, 53, 265
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 265,840,156,836, is 1.
Now, the common factors can be found like this.
265:5x 53
840:2x 2x 2x 3x 5x 7
156:2x 2x 3x 13
836:2x 2x 11x 19
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 29030601600/(1x240)
LCM = 29030601600/240
LCM = 120960840
Thus, we can understand that the LCM of 265,840,156,836 is 120960840.
