Find LCM of 322,398,459,765,778 with Prime Factorization
| 2 | 322, 398, 459, 765, 778 |
| 3 | 161, 199, 459, 765, 389 |
| 3 | 161, 199, 153, 255, 389 |
| 17 | 161, 199, 51, 85, 389 |
| 161, 199, 3, 5, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 161 x 199 x 3 x 5 x 389 = 57205954890
Therefore, the lowest common multiple of 322,398,459,765,778 is 57205954890.
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.
322 x 398 x 459 x 765 x 778 = 35010044392680
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.
322 : 1, 2, 7, 14, 23, 46, 161, 322
398 : 1, 2, 199, 398
459 : 1, 3, 9, 17, 27, 51, 153, 459
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,398,459,765,778, is 1.
Now, the common factors can be found like this.
322:2x 7x 23
398:2x 199
459:3x 3x 3x 17
765:3x 3x 5x 17
778:2x 389
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 35010044392680/(1x612)
LCM = 35010044392680/612
LCM = 57205954890
Thus, we can understand that the LCM of 322,398,459,765,778 is 57205954890.
