Given numbers are 649,561,833,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,561,833,830 is 1346136330.
Find LCM of 649,561,833,830 with Prime Factorization
| 11 | 649, 561, 833, 830 |
| 17 | 59, 51, 833, 830 |
| 59, 3, 49, 830 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 59 x 3 x 49 x 830 = 1346136330
Therefore, the lowest common multiple of 649,561,833,830 is 1346136330.
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.
649 x 561 x 833 x 830 = 251727493710
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.
649 : 1, 11, 59, 649
561 : 1, 3, 11, 17, 33, 51, 187, 561
833 : 1, 7, 17, 49, 119, 833
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,561,833,830, is 1.
Now, the common factors can be found like this.
649:11x 59
561:3x 11x 17
833:7x 7x 17
830:2x 5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 251727493710/(1x187)
LCM = 251727493710/187
LCM = 1346136330
Thus, we can understand that the LCM of 649,561,833,830 is 1346136330.
