Find LCM of 782,766,392,245,213 with Prime Factorization
| 2 | 782, 766, 392, 245, 213 |
| 7 | 391, 383, 196, 245, 213 |
| 7 | 391, 383, 28, 35, 213 |
| 391, 383, 4, 5, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 391 x 383 x 4 x 5 x 213 = 62518882440
Therefore, the lowest common multiple of 782,766,392,245,213 is 62518882440.
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.
782 x 766 x 392 x 245 x 213 = 12253700958240
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
766 : 1, 2, 383, 766
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
245 : 1, 5, 7, 35, 49, 245
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,766,392,245,213, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
766:2x 383
392:2x 2x 2x 7x 7
245:5x 7x 7
213:3x 71
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 12253700958240/(1x196)
LCM = 12253700958240/196
LCM = 62518882440
Thus, we can understand that the LCM of 782,766,392,245,213 is 62518882440.
