Given numbers are 220,506,380,161,191
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,506,380,161,191 is 128539180.
Find LCM of 220,506,380,161,191 with Prime Factorization
| 2 | 220, 506, 380, 161, 191 |
| 2 | 110, 253, 190, 161, 191 |
| 5 | 55, 253, 95, 161, 191 |
| 11 | 11, 253, 19, 161, 191 |
| 23 | 1, 23, 19, 161, 191 |
| 1, 1, 19, 7, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 23 x 1 x 1 x 19 x 7 x 191 = 128539180
Therefore, the lowest common multiple of 220,506,380,161,191 is 128539180.
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.
220 x 506 x 380 x 161 x 191 = 1300816501600
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
506 : 1, 2, 11, 22, 23, 46, 253, 506
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
161 : 1, 7, 23, 161
191 : 1, 191
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,506,380,161,191, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
506:2x 11x 23
380:2x 2x 5x 19
161:7x 23
191:191
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 11x 23 = 10120
Therefore, the value for common factors is 10120.
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 = 1300816501600/(1x10120)
LCM = 1300816501600/10120
LCM = 128539180
Thus, we can understand that the LCM of 220,506,380,161,191 is 128539180.
