Given numbers are 623,990,371,106,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,990,371,106,655 is 4282234110.
Find LCM of 623,990,371,106,655 with Prime Factorization
| 2 | 623, 990, 371, 106, 655 |
| 5 | 623, 495, 371, 53, 655 |
| 7 | 623, 99, 371, 53, 131 |
| 53 | 89, 99, 53, 53, 131 |
| 89, 99, 1, 1, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 53 x 89 x 99 x 1 x 1 x 131 = 4282234110
Therefore, the lowest common multiple of 623,990,371,106,655 is 4282234110.
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.
623 x 990 x 371 x 106 x 655 = 15887088548100
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.
623 : 1, 7, 89, 623
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
371 : 1, 7, 53, 371
106 : 1, 2, 53, 106
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,990,371,106,655, is 1.
Now, the common factors can be found like this.
623:7x 89
990:2x 3x 3x 5x 11
371:7x 53
106:2x 53
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 53 = 3710
Therefore, the value for common factors is 3710.
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 = 15887088548100/(1x3710)
LCM = 15887088548100/3710
LCM = 4282234110
Thus, we can understand that the LCM of 623,990,371,106,655 is 4282234110.
