Given numbers are 211,889,392,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,889,392,381 is 31513272.
Find LCM of 211,889,392,381 with Prime Factorization
| 7 | 211, 889, 392, 381 |
| 127 | 211, 127, 56, 381 |
| 211, 1, 56, 3 |
Multiply the prime numbers at the bottom and the left side.
7 x 127 x 211 x 1 x 56 x 3 = 31513272
Therefore, the lowest common multiple of 211,889,392,381 is 31513272.
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.
211 x 889 x 392 x 381 = 28015298808
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.
211 : 1, 211
889 : 1, 7, 127, 889
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,889,392,381, is 1.
Now, the common factors can be found like this.
211:211
889:7x 127
392:2x 2x 2x 7x 7
381:3x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 127 = 889
Therefore, the value for common factors is 889.
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 = 28015298808/(1x889)
LCM = 28015298808/889
LCM = 31513272
Thus, we can understand that the LCM of 211,889,392,381 is 31513272.
