Given numbers are 319,155,180,260,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,155,180,260,770 is 161981820.
Find LCM of 319,155,180,260,770 with Prime Factorization
| 2 | 319, 155, 180, 260, 770 |
| 2 | 319, 155, 90, 130, 385 |
| 5 | 319, 155, 45, 65, 385 |
| 11 | 319, 31, 9, 13, 77 |
| 29, 31, 9, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 29 x 31 x 9 x 13 x 7 = 161981820
Therefore, the lowest common multiple of 319,155,180,260,770 is 161981820.
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.
319 x 155 x 180 x 260 x 770 = 1781800020000
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.
319 : 1, 11, 29, 319
155 : 1, 5, 31, 155
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,155,180,260,770, is 1.
Now, the common factors can be found like this.
319:11x 29
155:5x 31
180:2x 2x 3x 3x 5
260:2x 2x 5x 13
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 5x 5x 11 = 11000
Therefore, the value for common factors is 11000.
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 = 1781800020000/(1x11000)
LCM = 1781800020000/11000
LCM = 161981820
Thus, we can understand that the LCM of 319,155,180,260,770 is 161981820.
