Find LCM of 565,851,782,640,428 with Prime Factorization
| 2 | 565, 851, 782, 640, 428 |
| 2 | 565, 851, 391, 320, 214 |
| 5 | 565, 851, 391, 160, 107 |
| 23 | 113, 851, 391, 32, 107 |
| 113, 37, 17, 32, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 113 x 37 x 17 x 32 x 107 = 111949118080
Therefore, the lowest common multiple of 565,851,782,640,428 is 111949118080.
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.
565 x 851 x 782 x 640 x 428 = 102993188633600
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.
565 : 1, 5, 113, 565
851 : 1, 23, 37, 851
782 : 1, 2, 17, 23, 34, 46, 391, 782
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,851,782,640,428, is 1.
Now, the common factors can be found like this.
565:5x 113
851:23x 37
782:2x 17x 23
640:2x 2x 2x 2x 2x 2x 2x 5
428:2x 2x 107
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 2x 5x 23 = 920
Therefore, the value for common factors is 920.
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 = 102993188633600/(1x920)
LCM = 102993188633600/920
LCM = 111949118080
Thus, we can understand that the LCM of 565,851,782,640,428 is 111949118080.
