Find LCM of 655,294,443,168,530 with Prime Factorization
| 2 | 655, 294, 443, 168, 530 |
| 3 | 655, 147, 443, 84, 265 |
| 5 | 655, 49, 443, 28, 265 |
| 7 | 131, 49, 443, 28, 53 |
| 131, 7, 443, 4, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 131 x 7 x 443 x 4 x 53 = 18085404120
Therefore, the lowest common multiple of 655,294,443,168,530 is 18085404120.
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.
655 x 294 x 443 x 168 x 530 = 7595869730400
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.
655 : 1, 5, 131, 655
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
443 : 1, 443
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
530 : 1, 2, 5, 10, 53, 106, 265, 530
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,294,443,168,530, is 1.
Now, the common factors can be found like this.
655:5x 131
294:2x 3x 7x 7
443:443
168:2x 2x 2x 3x 7
530:2x 5x 53
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 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 7595869730400/(1x420)
LCM = 7595869730400/420
LCM = 18085404120
Thus, we can understand that the LCM of 655,294,443,168,530 is 18085404120.
