Given numbers are 671,732,551,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,732,551,722 is 84296388.
Find LCM of 671,732,551,722 with Prime Factorization
| 2 | 671, 732, 551, 722 |
| 19 | 671, 366, 551, 361 |
| 61 | 671, 366, 29, 19 |
| 11, 6, 29, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 61 x 11 x 6 x 29 x 19 = 84296388
Therefore, the lowest common multiple of 671,732,551,722 is 84296388.
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.
671 x 732 x 551 x 722 = 195399027384
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.
671 : 1, 11, 61, 671
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
551 : 1, 19, 29, 551
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,732,551,722, is 1.
Now, the common factors can be found like this.
671:11x 61
732:2x 2x 3x 61
551:19x 29
722:2x 19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 61 = 2318
Therefore, the value for common factors is 2318.
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 = 195399027384/(1x2318)
LCM = 195399027384/2318
LCM = 84296388
Thus, we can understand that the LCM of 671,732,551,722 is 84296388.
