Find LCM of 647,546,202,445,819 with Prime Factorization
2 | 647, 546, 202, 445, 819 |
3 | 647, 273, 101, 445, 819 |
7 | 647, 91, 101, 445, 273 |
13 | 647, 13, 101, 445, 39 |
647, 1, 101, 445, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 647 x 1 x 101 x 445 x 3 = 47632081770
Therefore, the lowest common multiple of 647,546,202,445,819 is 47632081770.
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.
647 x 546 x 202 x 445 x 819 = 26007116646420
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.
647 : 1, 647
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
202 : 1, 2, 101, 202
445 : 1, 5, 89, 445
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,546,202,445,819, is 1.
Now, the common factors can be found like this.
647:647
546:2x 3x 7x 13
202:2x 101
445:5x 89
819:3x 3x 7x 13
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 7x 13 = 546
Therefore, the value for common factors is 546.
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 = 26007116646420/(1x546)
LCM = 26007116646420/546
LCM = 47632081770
Thus, we can understand that the LCM of 647,546,202,445,819 is 47632081770.
