Find LCM of 294,510,717,221,390 with Prime Factorization
2 | 294, 510, 717, 221, 390 |
3 | 147, 255, 717, 221, 195 |
5 | 49, 85, 239, 221, 65 |
13 | 49, 17, 239, 221, 13 |
17 | 49, 17, 239, 17, 1 |
49, 1, 239, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 17 x 49 x 1 x 239 x 1 x 1 = 77643930
Therefore, the lowest common multiple of 294,510,717,221,390 is 77643930.
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.
294 x 510 x 717 x 221 x 390 = 9266026606200
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.
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
717 : 1, 3, 239, 717
221 : 1, 13, 17, 221
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 294,510,717,221,390, is 1.
Now, the common factors can be found like this.
294:2x 3x 7x 7
510:2x 3x 5x 17
717:3x 239
221:13x 17
390:2x 3x 5x 13
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 3x 3x 3x 5x 13x 17 = 119340
Therefore, the value for common factors is 119340.
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 = 9266026606200/(1x119340)
LCM = 9266026606200/119340
LCM = 77643930
Thus, we can understand that the LCM of 294,510,717,221,390 is 77643930.
