Find LCM of 189,969,828,399,247 with Prime Factorization
3 | 189, 969, 828, 399, 247 |
3 | 63, 323, 276, 133, 247 |
7 | 21, 323, 92, 133, 247 |
19 | 3, 323, 92, 19, 247 |
3, 17, 92, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 19 x 3 x 17 x 92 x 1 x 13 = 73012212
Therefore, the lowest common multiple of 189,969,828,399,247 is 73012212.
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.
189 x 969 x 828 x 399 x 247 = 14944650637644
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
969 : 1, 3, 17, 19, 51, 57, 323, 969
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
399 : 1, 3, 7, 19, 21, 57, 133, 399
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,969,828,399,247, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
969:3x 17x 19
828:2x 2x 3x 3x 23
399:3x 7x 19
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7x 19x 19 = 204687
Therefore, the value for common factors is 204687.
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 = 14944650637644/(1x204687)
LCM = 14944650637644/204687
LCM = 73012212
Thus, we can understand that the LCM of 189,969,828,399,247 is 73012212.
