Find LCM of 765,145,308,354,178 with Prime Factorization
| 2 | 765, 145, 308, 354, 178 |
| 3 | 765, 145, 154, 177, 89 |
| 5 | 255, 145, 154, 59, 89 |
| 51, 29, 154, 59, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 51 x 29 x 154 x 59 x 89 = 35879977980
Therefore, the lowest common multiple of 765,145,308,354,178 is 35879977980.
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.
765 x 145 x 308 x 354 x 178 = 2152798678800
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
145 : 1, 5, 29, 145
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
354 : 1, 2, 3, 6, 59, 118, 177, 354
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,145,308,354,178, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
145:5x 29
308:2x 2x 7x 11
354:2x 3x 59
178:2x 89
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 5 = 60
Therefore, the value for common factors is 60.
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 = 2152798678800/(1x60)
LCM = 2152798678800/60
LCM = 35879977980
Thus, we can understand that the LCM of 765,145,308,354,178 is 35879977980.
