The LCM of 874,644,399,853 is 31311924.
Find LCM of 874,644,399,853 with Prime Factorization
| 2 | 874, 644, 399, 853 |
| 7 | 437, 322, 399, 853 |
| 19 | 437, 46, 57, 853 |
| 23 | 23, 46, 3, 853 |
| 1, 2, 3, 853 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 23 x 1 x 2 x 3 x 853 = 31311924
Therefore, the lowest common multiple of 874,644,399,853 is 31311924.
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.
874 x 644 x 399 x 853 = 191566351032
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
399 : 1, 3, 7, 19, 21, 57, 133, 399
853 : 1, 853
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,644,399,853, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
644:2x 2x 7x 23
399:3x 7x 19
853:853
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19x 23 = 6118
Therefore, the value for common factors is 6118.
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 = 191566351032/(1x6118)
LCM = 191566351032/6118
LCM = 31311924
Thus, we can understand that the LCM of 874,644,399,853 is 31311924.
