Given numbers are 746,876,862,861,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,876,862,861,636 is 2142140609868.
Find LCM of 746,876,862,861,636 with Prime Factorization
| 2 | 746, 876, 862, 861, 636 |
| 2 | 373, 438, 431, 861, 318 |
| 3 | 373, 219, 431, 861, 159 |
| 373, 73, 431, 287, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 373 x 73 x 431 x 287 x 53 = 2142140609868
Therefore, the lowest common multiple of 746,876,862,861,636 is 2142140609868.
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.
746 x 876 x 862 x 861 x 636 = 308468247820992
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.
746 : 1, 2, 373, 746
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
862 : 1, 2, 431, 862
861 : 1, 3, 7, 21, 41, 123, 287, 861
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,876,862,861,636, is 1.
Now, the common factors can be found like this.
746:2x 373
876:2x 2x 3x 73
862:2x 431
861:3x 7x 41
636:2x 2x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 308468247820992/(1x144)
LCM = 308468247820992/144
LCM = 2142140609868
Thus, we can understand that the LCM of 746,876,862,861,636 is 2142140609868.
