Find LCM of 247,180,630,381,239 with Prime Factorization
2 | 247, 180, 630, 381, 239 |
3 | 247, 90, 315, 381, 239 |
3 | 247, 30, 105, 127, 239 |
5 | 247, 10, 35, 127, 239 |
247, 2, 7, 127, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 247 x 2 x 7 x 127 x 239 = 9446460660
Therefore, the lowest common multiple of 247,180,630,381,239 is 9446460660.
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.
247 x 180 x 630 x 381 x 239 = 2550544378200
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.
247 : 1, 13, 19, 247
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
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
381 : 1, 3, 127, 381
239 : 1, 239
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,180,630,381,239, is 1.
Now, the common factors can be found like this.
247:13x 19
180:2x 2x 3x 3x 5
630:2x 3x 3x 5x 7
381:3x 127
239:239
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 5 = 270
Therefore, the value for common factors is 270.
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 = 2550544378200/(1x270)
LCM = 2550544378200/270
LCM = 9446460660
Thus, we can understand that the LCM of 247,180,630,381,239 is 9446460660.
