Given numbers are 178,880,890,130,206
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,880,890,130,206 is 104870480.
Find LCM of 178,880,890,130,206 with Prime Factorization
| 2 | 178, 880, 890, 130, 206 |
| 5 | 89, 440, 445, 65, 103 |
| 89 | 89, 88, 89, 13, 103 |
| 1, 88, 1, 13, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 89 x 1 x 88 x 1 x 13 x 103 = 104870480
Therefore, the lowest common multiple of 178,880,890,130,206 is 104870480.
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.
178 x 880 x 890 x 130 x 206 = 3733389088000
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.
178 : 1, 2, 89, 178
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
890 : 1, 2, 5, 10, 89, 178, 445, 890
130 : 1, 2, 5, 10, 13, 26, 65, 130
206 : 1, 2, 103, 206
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,880,890,130,206, is 2.
Now, the common factors can be found like this.
178:2x 89
880:2x 2x 2x 2x 5x 11
890:2x 5x 89
130:2x 5x 13
206:2x 103
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 89 = 17800
Therefore, the value for common factors is 17800.
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 = 3733389088000/(2x17800)
LCM = 3733389088000/35600
LCM = 104870480
Thus, we can understand that the LCM of 178,880,890,130,206 is 104870480.
