Given numbers are 743,851,329,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,851,329,161 is 208024397.
Find LCM of 743,851,329,161 with Prime Factorization
| 7 | 743, 851, 329, 161 |
| 23 | 743, 851, 47, 23 |
| 743, 37, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 743 x 37 x 47 x 1 = 208024397
Therefore, the lowest common multiple of 743,851,329,161 is 208024397.
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.
743 x 851 x 329 x 161 = 33491927917
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.
743 : 1, 743
851 : 1, 23, 37, 851
329 : 1, 7, 47, 329
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,851,329,161, is 1.
Now, the common factors can be found like this.
743:743
851:23x 37
329:7x 47
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 33491927917/(1x161)
LCM = 33491927917/161
LCM = 208024397
Thus, we can understand that the LCM of 743,851,329,161 is 208024397.
