Given numbers are 636,681,742,923,683
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,681,742,923,683 is 637093857036.
Find LCM of 636,681,742,923,683 with Prime Factorization
| 2 | 636, 681, 742, 923, 683 |
| 3 | 318, 681, 371, 923, 683 |
| 53 | 106, 227, 371, 923, 683 |
| 2, 227, 7, 923, 683 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 53 x 2 x 227 x 7 x 923 x 683 = 637093857036
Therefore, the lowest common multiple of 636,681,742,923,683 is 637093857036.
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.
636 x 681 x 742 x 923 x 683 = 202595846537448
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
681 : 1, 3, 227, 681
742 : 1, 2, 7, 14, 53, 106, 371, 742
923 : 1, 13, 71, 923
683 : 1, 683
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,681,742,923,683, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
681:3x 227
742:2x 7x 53
923:13x 71
683:683
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 53 = 318
Therefore, the value for common factors is 318.
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 = 202595846537448/(1x318)
LCM = 202595846537448/318
LCM = 637093857036
Thus, we can understand that the LCM of 636,681,742,923,683 is 637093857036.
