Given numbers are 624,895,172,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 624,895,172,728 is 168102480.
Find LCM of 624,895,172,728 with Prime Factorization
| 2 | 624, 895, 172, 728 |
| 2 | 312, 895, 86, 364 |
| 2 | 156, 895, 43, 182 |
| 13 | 78, 895, 43, 91 |
| 6, 895, 43, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 6 x 895 x 43 x 7 = 168102480
Therefore, the lowest common multiple of 624,895,172,728 is 168102480.
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.
624 x 895 x 172 x 728 = 69930631680
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
895 : 1, 5, 179, 895
172 : 1, 2, 4, 43, 86, 172
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,895,172,728, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
895:5x 179
172:2x 2x 43
728:2x 2x 2x 7x 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 13 = 416
Therefore, the value for common factors is 416.
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 = 69930631680/(1x416)
LCM = 69930631680/416
LCM = 168102480
Thus, we can understand that the LCM of 624,895,172,728 is 168102480.
