Given numbers are 602,645,217,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 602,645,217,123 is 11477130.
Find LCM of 602,645,217,123 with Prime Factorization
| 3 | 602, 645, 217, 123 |
| 7 | 602, 215, 217, 41 |
| 43 | 86, 215, 31, 41 |
| 2, 5, 31, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 43 x 2 x 5 x 31 x 41 = 11477130
Therefore, the lowest common multiple of 602,645,217,123 is 11477130.
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.
602 x 645 x 217 x 123 = 10363848390
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.
602 : 1, 2, 7, 14, 43, 86, 301, 602
645 : 1, 3, 5, 15, 43, 129, 215, 645
217 : 1, 7, 31, 217
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 602,645,217,123, is 1.
Now, the common factors can be found like this.
602:2x 7x 43
645:3x 5x 43
217:7x 31
123:3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 43 = 903
Therefore, the value for common factors is 903.
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 = 10363848390/(1x903)
LCM = 10363848390/903
LCM = 11477130
Thus, we can understand that the LCM of 602,645,217,123 is 11477130.
