Find LCM of 819,861,572,845,745 with Prime Factorization
3 | 819, 861, 572, 845, 745 |
5 | 273, 287, 572, 845, 745 |
7 | 273, 287, 572, 169, 149 |
13 | 39, 41, 572, 169, 149 |
3, 41, 44, 13, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 13 x 3 x 41 x 44 x 13 x 149 = 14309355060
Therefore, the lowest common multiple of 819,861,572,845,745 is 14309355060.
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.
819 x 861 x 572 x 845 x 745 = 253919505539700
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
861 : 1, 3, 7, 21, 41, 123, 287, 861
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
845 : 1, 5, 13, 65, 169, 845
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,861,572,845,745, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
861:3x 7x 41
572:2x 2x 11x 13
845:5x 13x 13
745:5x 149
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 7x 13x 13 = 17745
Therefore, the value for common factors is 17745.
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 = 253919505539700/(1x17745)
LCM = 253919505539700/17745
LCM = 14309355060
Thus, we can understand that the LCM of 819,861,572,845,745 is 14309355060.
