Find LCM of 279,126,630,131,155 with Prime Factorization
| 2 | 279, 126, 630, 131, 155 |
| 3 | 279, 63, 315, 131, 155 |
| 3 | 93, 21, 105, 131, 155 |
| 5 | 31, 7, 35, 131, 155 |
| 7 | 31, 7, 7, 131, 31 |
| 31 | 31, 1, 1, 131, 31 |
| 1, 1, 1, 131, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 31 x 1 x 1 x 1 x 131 x 1 = 2558430
Therefore, the lowest common multiple of 279,126,630,131,155 is 2558430.
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.
279 x 126 x 630 x 131 x 155 = 449695241100
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.
279 : 1, 3, 9, 31, 93, 279
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
131 : 1, 131
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,126,630,131,155, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
126:2x 3x 3x 7
630:2x 3x 3x 5x 7
131:131
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 5x 7x 31 = 175770
Therefore, the value for common factors is 175770.
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 = 449695241100/(1x175770)
LCM = 449695241100/175770
LCM = 2558430
Thus, we can understand that the LCM of 279,126,630,131,155 is 2558430.
