Given numbers are 682,572,136,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,572,136,871 is 40393496.
Find LCM of 682,572,136,871 with Prime Factorization
| 2 | 682, 572, 136, 871 |
| 2 | 341, 286, 68, 871 |
| 11 | 341, 143, 34, 871 |
| 13 | 31, 13, 34, 871 |
| 31, 1, 34, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 31 x 1 x 34 x 67 = 40393496
Therefore, the lowest common multiple of 682,572,136,871 is 40393496.
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.
682 x 572 x 136 x 871 = 46210159424
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
136 : 1, 2, 4, 8, 17, 34, 68, 136
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,572,136,871, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
572:2x 2x 11x 13
136:2x 2x 2x 17
871:13x 67
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 11x 13 = 1144
Therefore, the value for common factors is 1144.
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 = 46210159424/(1x1144)
LCM = 46210159424/1144
LCM = 40393496
Thus, we can understand that the LCM of 682,572,136,871 is 40393496.
