Find LCM of 724,942,387,252 with Prime Factorization
| 2 | 724, 942, 387, 252 |
| 2 | 362, 471, 387, 126 |
| 3 | 181, 471, 387, 63 |
| 3 | 181, 157, 129, 21 |
| 181, 157, 43, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 181 x 157 x 43 x 7 = 307926612
Therefore, the lowest common multiple of 724,942,387,252 is 307926612.
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.
724 x 942 x 387 x 252 = 66512148192
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.
724 : 1, 2, 4, 181, 362, 724
942 : 1, 2, 3, 6, 157, 314, 471, 942
387 : 1, 3, 9, 43, 129, 387
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,942,387,252, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
942:2x 3x 157
387:3x 3x 43
252:2x 2x 3x 3x 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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 66512148192/(1x216)
LCM = 66512148192/216
LCM = 307926612
Thus, we can understand that the LCM of 724,942,387,252 is 307926612.
