Find LCM of 861,715,366,366,491 with Prime Factorization
2 | 861, 715, 366, 366, 491 |
3 | 861, 715, 183, 183, 491 |
61 | 287, 715, 61, 61, 491 |
287, 715, 1, 1, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 61 x 287 x 715 x 1 x 1 x 491 = 36876569730
Therefore, the lowest common multiple of 861,715,366,366,491 is 36876569730.
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 715 x 366 x 366 x 491 = 40490473563540
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
366 : 1, 2, 3, 6, 61, 122, 183, 366
366 : 1, 2, 3, 6, 61, 122, 183, 366
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,715,366,366,491, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
715:5x 11x 13
366:2x 3x 61
366:2x 3x 61
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 61 = 1098
Therefore, the value for common factors is 1098.
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 = 40490473563540/(1x1098)
LCM = 40490473563540/1098
LCM = 36876569730
Thus, we can understand that the LCM of 861,715,366,366,491 is 36876569730.
