Find LCM of 340,248,528,461,390 with Prime Factorization
| 2 | 340, 248, 528, 461, 390 |
| 2 | 170, 124, 264, 461, 195 |
| 2 | 85, 62, 132, 461, 195 |
| 3 | 85, 31, 66, 461, 195 |
| 5 | 85, 31, 22, 461, 65 |
| 17, 31, 22, 461, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 31 x 22 x 461 x 13 = 8337941040
Therefore, the lowest common multiple of 340,248,528,461,390 is 8337941040.
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.
340 x 248 x 528 x 461 x 390 = 8004423398400
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
248 : 1, 2, 4, 8, 31, 62, 124, 248
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
461 : 1, 461
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 340,248,528,461,390, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
248:2x 2x 2x 31
528:2x 2x 2x 2x 3x 11
461:461
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 2x 2x 2x 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 8004423398400/(1x960)
LCM = 8004423398400/960
LCM = 8337941040
Thus, we can understand that the LCM of 340,248,528,461,390 is 8337941040.
