Given numbers are 787,815,882,749,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,815,882,749,355 is 4297768838370.
Find LCM of 787,815,882,749,355 with Prime Factorization
| 5 | 787, 815, 882, 749, 355 |
| 7 | 787, 163, 882, 749, 71 |
| 787, 163, 126, 107, 71 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 787 x 163 x 126 x 107 x 71 = 4297768838370
Therefore, the lowest common multiple of 787,815,882,749,355 is 4297768838370.
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 815 x 882 x 749 x 355 = 150421909342950
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
815 : 1, 5, 163, 815
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
749 : 1, 7, 107, 749
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,815,882,749,355, is 1.
Now, the common factors can be found like this.
787:787
815:5x 163
882:2x 3x 3x 7x 7
749:7x 107
355:5x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 150421909342950/(1x35)
LCM = 150421909342950/35
LCM = 4297768838370
Thus, we can understand that the LCM of 787,815,882,749,355 is 4297768838370.
