Given numbers are 491,671,686,141,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,671,686,141,611 is 414276780918.
Find LCM of 491,671,686,141,611 with Prime Factorization
| 47 | 491, 671, 686, 141, 611 |
| 491, 671, 686, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
47 x 491 x 671 x 686 x 3 x 13 = 414276780918
Therefore, the lowest common multiple of 491,671,686,141,611 is 414276780918.
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.
491 x 671 x 686 x 141 x 611 = 19471008703146
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.
491 : 1, 491
671 : 1, 11, 61, 671
686 : 1, 2, 7, 14, 49, 98, 343, 686
141 : 1, 3, 47, 141
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,671,686,141,611, is 1.
Now, the common factors can be found like this.
491:491
671:11x 61
686:2x 7x 7x 7
141:3x 47
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
47 = 47
Therefore, the value for common factors is 47.
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 = 19471008703146/(1x47)
LCM = 19471008703146/47
LCM = 414276780918
Thus, we can understand that the LCM of 491,671,686,141,611 is 414276780918.
