Given numbers are 423,871,611,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,871,611,991 is 365117103.
Find LCM of 423,871,611,991 with Prime Factorization
| 13 | 423, 871, 611, 991 |
| 47 | 423, 67, 47, 991 |
| 9, 67, 1, 991 |
Multiply the prime numbers at the bottom and the left side.
13 x 47 x 9 x 67 x 1 x 991 = 365117103
Therefore, the lowest common multiple of 423,871,611,991 is 365117103.
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.
423 x 871 x 611 x 991 = 223086549933
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.
423 : 1, 3, 9, 47, 141, 423
871 : 1, 13, 67, 871
611 : 1, 13, 47, 611
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,871,611,991, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
871:13x 67
611:13x 47
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 47 = 611
Therefore, the value for common factors is 611.
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 = 223086549933/(1x611)
LCM = 223086549933/611
LCM = 365117103
Thus, we can understand that the LCM of 423,871,611,991 is 365117103.
