Find LCM of 321,918,378,508,424 with Prime Factorization
| 2 | 321, 918, 378, 508, 424 |
| 2 | 321, 459, 189, 254, 212 |
| 3 | 321, 459, 189, 127, 106 |
| 3 | 107, 153, 63, 127, 106 |
| 3 | 107, 51, 21, 127, 106 |
| 107, 17, 7, 127, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 107 x 17 x 7 x 127 x 106 = 18512457768
Therefore, the lowest common multiple of 321,918,378,508,424 is 18512457768.
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.
321 x 918 x 378 x 508 x 424 = 23992145267328
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.
321 : 1, 3, 107, 321
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
508 : 1, 2, 4, 127, 254, 508
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,918,378,508,424, is 1.
Now, the common factors can be found like this.
321:3x 107
918:2x 3x 3x 3x 17
378:2x 3x 3x 3x 7
508:2x 2x 127
424:2x 2x 2x 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 2x 2x 3x 3x 3x 3 = 1296
Therefore, the value for common factors is 1296.
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 = 23992145267328/(1x1296)
LCM = 23992145267328/1296
LCM = 18512457768
Thus, we can understand that the LCM of 321,918,378,508,424 is 18512457768.
