Given numbers are 668,153,374,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,153,374,203 is 228221532.
Find LCM of 668,153,374,203 with Prime Factorization
| 2 | 668, 153, 374, 203 |
| 17 | 334, 153, 187, 203 |
| 334, 9, 11, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 334 x 9 x 11 x 203 = 228221532
Therefore, the lowest common multiple of 668,153,374,203 is 228221532.
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 153 x 374 x 203 = 7759532088
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
153 : 1, 3, 9, 17, 51, 153
374 : 1, 2, 11, 17, 22, 34, 187, 374
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,153,374,203, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
153:3x 3x 17
374:2x 11x 17
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 7759532088/(1x34)
LCM = 7759532088/34
LCM = 228221532
Thus, we can understand that the LCM of 668,153,374,203 is 228221532.
