Given numbers are 664,871,399,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 664,871,399,422 is 48690203016.
Find LCM of 664,871,399,422 with Prime Factorization
2 | 664, 871, 399, 422 |
332, 871, 399, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 332 x 871 x 399 x 211 = 48690203016
Therefore, the lowest common multiple of 664,871,399,422 is 48690203016.
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.
664 x 871 x 399 x 422 = 97380406032
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
871 : 1, 13, 67, 871
399 : 1, 3, 7, 19, 21, 57, 133, 399
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,871,399,422, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
871:13x 67
399:3x 7x 19
422:2x 211
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 = 97380406032/(1x2)
LCM = 97380406032/2
LCM = 48690203016
Thus, we can understand that the LCM of 664,871,399,422 is 48690203016.
