Given numbers are 871,149,998,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,149,998,784 is 50771621264.
Find LCM of 871,149,998,784 with Prime Factorization
2 | 871, 149, 998, 784 |
871, 149, 499, 392 |
Multiply the prime numbers at the bottom and the left side.
2 x 871 x 149 x 499 x 392 = 50771621264
Therefore, the lowest common multiple of 871,149,998,784 is 50771621264.
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.
871 x 149 x 998 x 784 = 101543242528
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.
871 : 1, 13, 67, 871
149 : 1, 149
998 : 1, 2, 499, 998
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,149,998,784, is 1.
Now, the common factors can be found like this.
871:13x 67
149:149
998:2x 499
784:2x 2x 2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 101543242528/(1x2)
LCM = 101543242528/2
LCM = 50771621264
Thus, we can understand that the LCM of 871,149,998,784 is 50771621264.
