The LCM of 742,257,987,186,328 is 136697849736.
Find LCM of 742,257,987,186,328 with Prime Factorization
| 2 | 742, 257, 987, 186, 328 |
| 3 | 371, 257, 987, 93, 164 |
| 7 | 371, 257, 329, 31, 164 |
| 53, 257, 47, 31, 164 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 53 x 257 x 47 x 31 x 164 = 136697849736
Therefore, the lowest common multiple of 742,257,987,186,328 is 136697849736.
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.
742 x 257 x 987 x 186 x 328 = 11482619377824
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
257 : 1, 257
987 : 1, 3, 7, 21, 47, 141, 329, 987
186 : 1, 2, 3, 6, 31, 62, 93, 186
328 : 1, 2, 4, 8, 41, 82, 164, 328
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,257,987,186,328, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
257:257
987:3x 7x 47
186:2x 3x 31
328:2x 2x 2x 41
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 7 = 84
Therefore, the value for common factors is 84.
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 = 11482619377824/(1x84)
LCM = 11482619377824/84
LCM = 136697849736
Thus, we can understand that the LCM of 742,257,987,186,328 is 136697849736.
