Find LCM of 441,771,441,266,138 with Prime Factorization
| 2 | 441, 771, 441, 266, 138 |
| 3 | 441, 771, 441, 133, 69 |
| 3 | 147, 257, 147, 133, 23 |
| 7 | 49, 257, 49, 133, 23 |
| 7 | 7, 257, 7, 19, 23 |
| 1, 257, 1, 19, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 7 x 1 x 257 x 1 x 19 x 23 = 99056538
Therefore, the lowest common multiple of 441,771,441,266,138 is 99056538.
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.
441 x 771 x 441 x 266 x 138 = 5504175590508
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
771 : 1, 3, 257, 771
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
266 : 1, 2, 7, 14, 19, 38, 133, 266
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,771,441,266,138, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
771:3x 257
441:3x 3x 7x 7
266:2x 7x 19
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 7x 7x 7 = 55566
Therefore, the value for common factors is 55566.
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 = 5504175590508/(1x55566)
LCM = 5504175590508/55566
LCM = 99056538
Thus, we can understand that the LCM of 441,771,441,266,138 is 99056538.
