Given numbers are 668,702,668,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,702,668,251 is 58851468.
Find LCM of 668,702,668,251 with Prime Factorization
| 2 | 668, 702, 668, 251 |
| 2 | 334, 351, 334, 251 |
| 167 | 167, 351, 167, 251 |
| 1, 351, 1, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 167 x 1 x 351 x 1 x 251 = 58851468
Therefore, the lowest common multiple of 668,702,668,251 is 58851468.
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.
668 x 702 x 668 x 251 = 78625561248
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.
668 : 1, 2, 4, 167, 334, 668
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
668 : 1, 2, 4, 167, 334, 668
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,702,668,251, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
702:2x 3x 3x 3x 13
668:2x 2x 167
251:251
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 167 = 1336
Therefore, the value for common factors is 1336.
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 = 78625561248/(1x1336)
LCM = 78625561248/1336
LCM = 58851468
Thus, we can understand that the LCM of 668,702,668,251 is 58851468.
