Find LCM of 644,824,897,310,931 with Prime Factorization
| 2 | 644, 824, 897, 310, 931 |
| 2 | 322, 412, 897, 155, 931 |
| 7 | 161, 206, 897, 155, 931 |
| 23 | 23, 206, 897, 155, 133 |
| 1, 206, 39, 155, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 23 x 1 x 206 x 39 x 155 x 133 = 106659866040
Therefore, the lowest common multiple of 644,824,897,310,931 is 106659866040.
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.
644 x 824 x 897 x 310 x 931 = 137377907459520
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
824 : 1, 2, 4, 8, 103, 206, 412, 824
897 : 1, 3, 13, 23, 39, 69, 299, 897
310 : 1, 2, 5, 10, 31, 62, 155, 310
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,824,897,310,931, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
824:2x 2x 2x 103
897:3x 13x 23
310:2x 5x 31
931:7x 7x 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 7x 23 = 1288
Therefore, the value for common factors is 1288.
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 = 137377907459520/(1x1288)
LCM = 137377907459520/1288
LCM = 106659866040
Thus, we can understand that the LCM of 644,824,897,310,931 is 106659866040.
