Given numbers are 821,838,393,492,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,838,393,492,889 is 19710395534172.
Find LCM of 821,838,393,492,889 with Prime Factorization
| 2 | 821, 838, 393, 492, 889 |
| 3 | 821, 419, 393, 246, 889 |
| 821, 419, 131, 82, 889 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 821 x 419 x 131 x 82 x 889 = 19710395534172
Therefore, the lowest common multiple of 821,838,393,492,889 is 19710395534172.
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.
821 x 838 x 393 x 492 x 889 = 118262373205032
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.
821 : 1, 821
838 : 1, 2, 419, 838
393 : 1, 3, 131, 393
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,838,393,492,889, is 1.
Now, the common factors can be found like this.
821:821
838:2x 419
393:3x 131
492:2x 2x 3x 41
889:7x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 118262373205032/(1x6)
LCM = 118262373205032/6
LCM = 19710395534172
Thus, we can understand that the LCM of 821,838,393,492,889 is 19710395534172.
