Given numbers are 649,786,118,961,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,786,118,961,431 is 211284627774.
Find LCM of 649,786,118,961,431 with Prime Factorization
| 2 | 649, 786, 118, 961, 431 |
| 59 | 649, 393, 59, 961, 431 |
| 11, 393, 1, 961, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 59 x 11 x 393 x 1 x 961 x 431 = 211284627774
Therefore, the lowest common multiple of 649,786,118,961,431 is 211284627774.
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 786 x 118 x 961 x 431 = 24931586077332
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
786 : 1, 2, 3, 6, 131, 262, 393, 786
118 : 1, 2, 59, 118
961 : 1, 31, 961
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,786,118,961,431, is 1.
Now, the common factors can be found like this.
649:11x 59
786:2x 3x 131
118:2x 59
961:31x 31
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 59 = 118
Therefore, the value for common factors is 118.
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 = 24931586077332/(1x118)
LCM = 24931586077332/118
LCM = 211284627774
Thus, we can understand that the LCM of 649,786,118,961,431 is 211284627774.
