Find LCM of 416,243,782,782,905 with Prime Factorization
2 | 416, 243, 782, 782, 905 |
17 | 208, 243, 391, 391, 905 |
23 | 208, 243, 23, 23, 905 |
208, 243, 1, 1, 905 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 208 x 243 x 1 x 1 x 905 = 35770494240
Therefore, the lowest common multiple of 416,243,782,782,905 is 35770494240.
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.
416 x 243 x 782 x 782 x 905 = 55945052991360
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
243 : 1, 3, 9, 27, 81, 243
782 : 1, 2, 17, 23, 34, 46, 391, 782
782 : 1, 2, 17, 23, 34, 46, 391, 782
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,243,782,782,905, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
243:3x 3x 3x 3x 3
782:2x 17x 23
782:2x 17x 23
905:5x 181
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 17x 23 = 1564
Therefore, the value for common factors is 1564.
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 = 55945052991360/(1x1564)
LCM = 55945052991360/1564
LCM = 35770494240
Thus, we can understand that the LCM of 416,243,782,782,905 is 35770494240.
