Given numbers are 787,681,717,624,268
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,681,717,624,268 is 1785080816688.
Find LCM of 787,681,717,624,268 with Prime Factorization
| 2 | 787, 681, 717, 624, 268 |
| 2 | 787, 681, 717, 312, 134 |
| 3 | 787, 681, 717, 156, 67 |
| 787, 227, 239, 52, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 787 x 227 x 239 x 52 x 67 = 1785080816688
Therefore, the lowest common multiple of 787,681,717,624,268 is 1785080816688.
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.
787 x 681 x 717 x 624 x 268 = 64262909400768
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.
787 : 1, 787
681 : 1, 3, 227, 681
717 : 1, 3, 239, 717
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
268 : 1, 2, 4, 67, 134, 268
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,681,717,624,268, is 1.
Now, the common factors can be found like this.
787:787
681:3x 227
717:3x 239
624:2x 2x 2x 2x 3x 13
268:2x 2x 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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 64262909400768/(1x36)
LCM = 64262909400768/36
LCM = 1785080816688
Thus, we can understand that the LCM of 787,681,717,624,268 is 1785080816688.
