The LCM of 308,357,386,478,978 is 118103755308.
Find LCM of 308,357,386,478,978 with Prime Factorization
2 | 308, 357, 386, 478, 978 |
3 | 154, 357, 193, 239, 489 |
7 | 154, 119, 193, 239, 163 |
22, 17, 193, 239, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 22 x 17 x 193 x 239 x 163 = 118103755308
Therefore, the lowest common multiple of 308,357,386,478,978 is 118103755308.
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.
308 x 357 x 386 x 478 x 978 = 19841430891744
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
357 : 1, 3, 7, 17, 21, 51, 119, 357
386 : 1, 2, 193, 386
478 : 1, 2, 239, 478
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,357,386,478,978, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
357:3x 7x 17
386:2x 193
478:2x 239
978:2x 3x 163
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 = 19841430891744/(1x168)
LCM = 19841430891744/168
LCM = 118103755308
Thus, we can understand that the LCM of 308,357,386,478,978 is 118103755308.
