Given numbers are 861,835,684,605,473
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,835,684,605,473 is 852861087540.
Find LCM of 861,835,684,605,473 with Prime Factorization
3 | 861, 835, 684, 605, 473 |
5 | 287, 835, 228, 605, 473 |
11 | 287, 167, 228, 121, 473 |
287, 167, 228, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 287 x 167 x 228 x 11 x 43 = 852861087540
Therefore, the lowest common multiple of 861,835,684,605,473 is 852861087540.
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.
861 x 835 x 684 x 605 x 473 = 140722079444100
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
835 : 1, 5, 167, 835
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
605 : 1, 5, 11, 55, 121, 605
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,835,684,605,473, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
835:5x 167
684:2x 2x 3x 3x 19
605:5x 11x 11
473:11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 140722079444100/(1x165)
LCM = 140722079444100/165
LCM = 852861087540
Thus, we can understand that the LCM of 861,835,684,605,473 is 852861087540.
