Given numbers are 161,449,851,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,449,851,808 is 2161151944.
Find LCM of 161,449,851,808 with Prime Factorization
23 | 161, 449, 851, 808 |
7, 449, 37, 808 |
Multiply the prime numbers at the bottom and the left side.
23 x 7 x 449 x 37 x 808 = 2161151944
Therefore, the lowest common multiple of 161,449,851,808 is 2161151944.
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.
161 x 449 x 851 x 808 = 49706494712
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.
161 : 1, 7, 23, 161
449 : 1, 449
851 : 1, 23, 37, 851
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,449,851,808, is 1.
Now, the common factors can be found like this.
161:7x 23
449:449
851:23x 37
808:2x 2x 2x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 49706494712/(1x23)
LCM = 49706494712/23
LCM = 2161151944
Thus, we can understand that the LCM of 161,449,851,808 is 2161151944.
