Find LCM of 368,945,156,765 with Prime Factorization
| 2 | 368, 945, 156, 765 |
| 2 | 184, 945, 78, 765 |
| 3 | 92, 945, 39, 765 |
| 3 | 92, 315, 13, 255 |
| 5 | 92, 105, 13, 85 |
| 92, 21, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 92 x 21 x 13 x 17 = 76854960
Therefore, the lowest common multiple of 368,945,156,765 is 76854960.
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.
368 x 945 x 156 x 765 = 41501678400
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,945,156,765, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
945:3x 3x 3x 5x 7
156:2x 2x 3x 13
765:3x 3x 5x 17
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 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 41501678400/(1x540)
LCM = 41501678400/540
LCM = 76854960
Thus, we can understand that the LCM of 368,945,156,765 is 76854960.
