Given numbers are 684,198,716,472
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,198,716,472 is 158921928.
Find LCM of 684,198,716,472 with Prime Factorization
| 2 | 684, 198, 716, 472 |
| 2 | 342, 99, 358, 236 |
| 3 | 171, 99, 179, 118 |
| 3 | 57, 33, 179, 118 |
| 19, 11, 179, 118 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 11 x 179 x 118 = 158921928
Therefore, the lowest common multiple of 684,198,716,472 is 158921928.
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.
684 x 198 x 716 x 472 = 45769515264
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
716 : 1, 2, 4, 179, 358, 716
472 : 1, 2, 4, 8, 59, 118, 236, 472
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,198,716,472, is 2.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
198:2x 3x 3x 11
716:2x 2x 179
472:2x 2x 2x 59
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 3 = 144
Therefore, the value for common factors is 144.
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 = 45769515264/(2x144)
LCM = 45769515264/288
LCM = 158921928
Thus, we can understand that the LCM of 684,198,716,472 is 158921928.
