Find LCM of 714,716,308,207,421 with Prime Factorization
| 2 | 714, 716, 308, 207, 421 |
| 2 | 357, 358, 154, 207, 421 |
| 3 | 357, 179, 77, 207, 421 |
| 7 | 119, 179, 77, 69, 421 |
| 17, 179, 11, 69, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 17 x 179 x 11 x 69 x 421 = 81678002868
Therefore, the lowest common multiple of 714,716,308,207,421 is 81678002868.
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.
714 x 716 x 308 x 207 x 421 = 13721904481824
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
716 : 1, 2, 4, 179, 358, 716
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
207 : 1, 3, 9, 23, 69, 207
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,716,308,207,421, is 1.
Now, the common factors can be found like this.
714:2x 3x 7x 17
716:2x 2x 179
308:2x 2x 7x 11
207:3x 3x 23
421:421
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 13721904481824/(1x168)
LCM = 13721904481824/168
LCM = 81678002868
Thus, we can understand that the LCM of 714,716,308,207,421 is 81678002868.
