The LCM of 441,684,221,684 is 7407036.
Find LCM of 441,684,221,684 with Prime Factorization
2 | 441, 684, 221, 684 |
2 | 441, 342, 221, 342 |
3 | 441, 171, 221, 171 |
3 | 147, 57, 221, 57 |
19 | 49, 19, 221, 19 |
49, 1, 221, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 49 x 1 x 221 x 1 = 7407036
Therefore, the lowest common multiple of 441,684,221,684 is 7407036.
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 684 x 221 x 684 = 45597713616
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
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
221 : 1, 13, 17, 221
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,684,221,684, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
684:2x 2x 3x 3x 19
221:13x 17
684:2x 2x 3x 3x 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 3x 3x 3x 3x 19 = 6156
Therefore, the value for common factors is 6156.
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 = 45597713616/(1x6156)
LCM = 45597713616/6156
LCM = 7407036
Thus, we can understand that the LCM of 441,684,221,684 is 7407036.
