Given numbers are 401,824,874,871,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,824,874,871,721 is 880378070936.
Find LCM of 401,824,874,871,721 with Prime Factorization
| 2 | 401, 824, 874, 871, 721 |
| 103 | 401, 412, 437, 871, 721 |
| 401, 4, 437, 871, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 103 x 401 x 4 x 437 x 871 x 7 = 880378070936
Therefore, the lowest common multiple of 401,824,874,871,721 is 880378070936.
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.
401 x 824 x 874 x 871 x 721 = 181357882612816
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.
401 : 1, 401
824 : 1, 2, 4, 8, 103, 206, 412, 824
874 : 1, 2, 19, 23, 38, 46, 437, 874
871 : 1, 13, 67, 871
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,824,874,871,721, is 1.
Now, the common factors can be found like this.
401:401
824:2x 2x 2x 103
874:2x 19x 23
871:13x 67
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 103 = 206
Therefore, the value for common factors is 206.
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 = 181357882612816/(1x206)
LCM = 181357882612816/206
LCM = 880378070936
Thus, we can understand that the LCM of 401,824,874,871,721 is 880378070936.
