Given numbers are 833,855,133,931,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 833,855,133,931,245 is 712215.
Find LCM of 833,855,133,931,245 with Prime Factorization
| 5 | 833, 855, 133, 931, 245 |
| 7 | 833, 171, 133, 931, 49 |
| 7 | 119, 171, 19, 133, 7 |
| 19 | 17, 171, 19, 19, 1 |
| 17, 9, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 7 x 19 x 17 x 9 x 1 x 1 x 1 = 712215
Therefore, the lowest common multiple of 833,855,133,931,245 is 712215.
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.
833 x 855 x 133 x 931 x 245 = 21606206496525
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.
833 : 1, 7, 17, 49, 119, 833
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
133 : 1, 7, 19, 133
931 : 1, 7, 19, 49, 133, 931
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,855,133,931,245, is 1.
Now, the common factors can be found like this.
833:7x 7x 17
855:3x 3x 5x 19
133:7x 19
931:7x 7x 19
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 7x 7x 7x 7x 19x 19 = 30336635
Therefore, the value for common factors is 30336635.
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 = 21606206496525/(1x30336635)
LCM = 21606206496525/30336635
LCM = 712215
Thus, we can understand that the LCM of 833,855,133,931,245 is 712215.
