Find LCM of 180,787,387,638,913 with Prime Factorization
2 | 180, 787, 387, 638, 913 |
3 | 90, 787, 387, 319, 913 |
3 | 30, 787, 129, 319, 913 |
11 | 10, 787, 43, 319, 913 |
10, 787, 43, 29, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 10 x 787 x 43 x 29 x 83 = 161281468260
Therefore, the lowest common multiple of 180,787,387,638,913 is 161281468260.
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.
180 x 787 x 387 x 638 x 913 = 31933730715480
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
787 : 1, 787
387 : 1, 3, 9, 43, 129, 387
638 : 1, 2, 11, 22, 29, 58, 319, 638
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,787,387,638,913, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
787:787
387:3x 3x 43
638:2x 11x 29
913:11x 83
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 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 31933730715480/(1x198)
LCM = 31933730715480/198
LCM = 161281468260
Thus, we can understand that the LCM of 180,787,387,638,913 is 161281468260.
