Find LCM of 294,492,658,100,686 with Prime Factorization
| 2 | 294, 492, 658, 100, 686 |
| 2 | 147, 246, 329, 50, 343 |
| 3 | 147, 123, 329, 25, 343 |
| 7 | 49, 41, 329, 25, 343 |
| 7 | 7, 41, 47, 25, 49 |
| 1, 41, 47, 25, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 7 x 1 x 41 x 47 x 25 x 7 = 198288300
Therefore, the lowest common multiple of 294,492,658,100,686 is 198288300.
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 492 x 658 x 100 x 686 = 6529237142400
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
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
658 : 1, 2, 7, 14, 47, 94, 329, 658
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
686 : 1, 2, 7, 14, 49, 98, 343, 686
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 294,492,658,100,686, is 2.
Now, the common factors can be found like this.
294:2x 3x 7x 7
492:2x 2x 3x 41
658:2x 7x 47
100:2x 2x 5x 5
686:2x 7x 7x 7
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 2x 3x 7x 7x 7 = 16464
Therefore, the value for common factors is 16464.
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 = 6529237142400/(2x16464)
LCM = 6529237142400/32928
LCM = 198288300
Thus, we can understand that the LCM of 294,492,658,100,686 is 198288300.
