Given numbers are 874,143,629,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,143,629,221 is 78613678.
Find LCM of 874,143,629,221 with Prime Factorization
13 | 874, 143, 629, 221 |
17 | 874, 11, 629, 17 |
874, 11, 37, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 874 x 11 x 37 x 1 = 78613678
Therefore, the lowest common multiple of 874,143,629,221 is 78613678.
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 143 x 629 x 221 = 17373622838
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
143 : 1, 11, 13, 143
629 : 1, 17, 37, 629
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,143,629,221, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
143:11x 13
629:17x 37
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 17373622838/(1x221)
LCM = 17373622838/221
LCM = 78613678
Thus, we can understand that the LCM of 874,143,629,221 is 78613678.
