Given numbers are 85,20,57,62,179
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 85,20,57,62,179 is 107539620.
Find LCM of 85,20,57,62,179 with Prime Factorization
| 2 | 85, 20, 57, 62, 179 |
| 5 | 85, 10, 57, 31, 179 |
| 17, 2, 57, 31, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 2 x 57 x 31 x 179 = 107539620
Therefore, the lowest common multiple of 85,20,57,62,179 is 107539620.
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.
85 x 20 x 57 x 62 x 179 = 1075396200
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.
85 : 1, 5, 17, 85
20 : 1, 2, 4, 5, 10, 20
57 : 1, 3, 19, 57
62 : 1, 2, 31, 62
179 : 1, 179
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 85,20,57,62,179, is 1.
Now, the common factors can be found like this.
85:5x 17
20:2x 2x 5
57:3x 19
62:2x 31
179:179
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 1075396200/(1x10)
LCM = 1075396200/10
LCM = 107539620
Thus, we can understand that the LCM of 85,20,57,62,179 is 107539620.
