The LCM of 781,429,768,860,507 is 21794023680.
Find LCM of 781,429,768,860,507 with Prime Factorization
| 2 | 781, 429, 768, 860, 507 |
| 2 | 781, 429, 384, 430, 507 |
| 3 | 781, 429, 192, 215, 507 |
| 11 | 781, 143, 64, 215, 169 |
| 13 | 71, 13, 64, 215, 169 |
| 71, 1, 64, 215, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 71 x 1 x 64 x 215 x 13 = 21794023680
Therefore, the lowest common multiple of 781,429,768,860,507 is 21794023680.
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.
781 x 429 x 768 x 860 x 507 = 112195633904640
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.
781 : 1, 11, 71, 781
429 : 1, 3, 11, 13, 33, 39, 143, 429
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,429,768,860,507, is 1.
Now, the common factors can be found like this.
781:11x 71
429:3x 11x 13
768:2x 2x 2x 2x 2x 2x 2x 2x 3
860:2x 2x 5x 43
507:3x 13x 13
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 3x 3x 11x 13 = 5148
Therefore, the value for common factors is 5148.
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 = 112195633904640/(1x5148)
LCM = 112195633904640/5148
LCM = 21794023680
Thus, we can understand that the LCM of 781,429,768,860,507 is 21794023680.
