Given numbers are 152,387,473,516
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 152,387,473,516 is 647064.
Find LCM of 152,387,473,516 with Prime Factorization
| 2 | 152, 387, 473, 516 |
| 2 | 76, 387, 473, 258 |
| 3 | 38, 387, 473, 129 |
| 43 | 38, 43, 473, 129 |
| 38, 1, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 38 x 1 x 11 x 3 = 647064
Therefore, the lowest common multiple of 152,387,473,516 is 647064.
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.
152 x 387 x 473 x 516 = 14357056032
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.
152 : 1, 2, 4, 8, 19, 38, 76, 152
387 : 1, 3, 9, 43, 129, 387
473 : 1, 11, 43, 473
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 152,387,473,516, is 1.
Now, the common factors can be found like this.
152:2x 2x 2x 19
387:3x 3x 43
473:11x 43
516:2x 2x 3x 43
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 43x 43 = 22188
Therefore, the value for common factors is 22188.
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 = 14357056032/(1x22188)
LCM = 14357056032/22188
LCM = 647064
Thus, we can understand that the LCM of 152,387,473,516 is 647064.
