Find LCM of 169,552,491,168,721 with Prime Factorization
2 | 169, 552, 491, 168, 721 |
2 | 169, 276, 491, 84, 721 |
2 | 169, 138, 491, 42, 721 |
3 | 169, 69, 491, 21, 721 |
7 | 169, 23, 491, 7, 721 |
169, 23, 491, 1, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 169 x 23 x 491 x 1 x 103 = 33024978168
Therefore, the lowest common multiple of 169,552,491,168,721 is 33024978168.
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.
169 x 552 x 491 x 168 x 721 = 5548196332224
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.
169 : 1, 13, 169
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
491 : 1, 491
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,552,491,168,721, is 1.
Now, the common factors can be found like this.
169:13x 13
552:2x 2x 2x 3x 23
491:491
168:2x 2x 2x 3x 7
721:7x 103
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 5548196332224/(1x168)
LCM = 5548196332224/168
LCM = 33024978168
Thus, we can understand that the LCM of 169,552,491,168,721 is 33024978168.
