Given numbers are 833,395,434,461,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 833,395,434,461,642 is 3018837556770.
Find LCM of 833,395,434,461,642 with Prime Factorization
| 2 | 833, 395, 434, 461, 642 |
| 7 | 833, 395, 217, 461, 321 |
| 119, 395, 31, 461, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 119 x 395 x 31 x 461 x 321 = 3018837556770
Therefore, the lowest common multiple of 833,395,434,461,642 is 3018837556770.
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 395 x 434 x 461 x 642 = 42263725794780
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
395 : 1, 5, 79, 395
434 : 1, 2, 7, 14, 31, 62, 217, 434
461 : 1, 461
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,395,434,461,642, is 1.
Now, the common factors can be found like this.
833:7x 7x 17
395:5x 79
434:2x 7x 31
461:461
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 42263725794780/(1x14)
LCM = 42263725794780/14
LCM = 3018837556770
Thus, we can understand that the LCM of 833,395,434,461,642 is 3018837556770.
