Find LCM of 627,644,897,931 with Prime Factorization
| 3 | 627, 644, 897, 931 |
| 7 | 209, 644, 299, 931 |
| 19 | 209, 92, 299, 133 |
| 23 | 11, 92, 299, 7 |
| 11, 4, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 23 x 11 x 4 x 13 x 7 = 36744708
Therefore, the lowest common multiple of 627,644,897,931 is 36744708.
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.
627 x 644 x 897 x 931 = 337206185316
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.
627 : 1, 3, 11, 19, 33, 57, 209, 627
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
897 : 1, 3, 13, 23, 39, 69, 299, 897
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 627,644,897,931, is 1.
Now, the common factors can be found like this.
627:3x 11x 19
644:2x 2x 7x 23
897:3x 13x 23
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.
3x 7x 19x 23 = 9177
Therefore, the value for common factors is 9177.
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 = 337206185316/(1x9177)
LCM = 337206185316/9177
LCM = 36744708
Thus, we can understand that the LCM of 627,644,897,931 is 36744708.
