Given numbers are 107,636,512,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,636,512,645 is 1872791040.
Find LCM of 107,636,512,645 with Prime Factorization
| 2 | 107, 636, 512, 645 |
| 2 | 107, 318, 256, 645 |
| 3 | 107, 159, 128, 645 |
| 107, 53, 128, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 53 x 128 x 215 = 1872791040
Therefore, the lowest common multiple of 107,636,512,645 is 1872791040.
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.
107 x 636 x 512 x 645 = 22473492480
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.
107 : 1, 107
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,636,512,645, is 1.
Now, the common factors can be found like this.
107:107
636:2x 2x 3x 53
512:2x 2x 2x 2x 2x 2x 2x 2x 2
645:3x 5x 43
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 3 = 12
Therefore, the value for common factors is 12.
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 = 22473492480/(1x12)
LCM = 22473492480/12
LCM = 1872791040
Thus, we can understand that the LCM of 107,636,512,645 is 1872791040.
