Given numbers are 768,916,940,270
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,916,940,270 is 371969280.
Find LCM of 768,916,940,270 with Prime Factorization
| 2 | 768, 916, 940, 270 |
| 2 | 384, 458, 470, 135 |
| 3 | 192, 229, 235, 135 |
| 5 | 64, 229, 235, 45 |
| 64, 229, 47, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 64 x 229 x 47 x 9 = 371969280
Therefore, the lowest common multiple of 768,916,940,270 is 371969280.
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.
768 x 916 x 940 x 270 = 178545254400
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
916 : 1, 2, 4, 229, 458, 916
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,916,940,270, is 2.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
916:2x 2x 229
940:2x 2x 5x 47
270:2x 3x 3x 3x 5
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 178545254400/(2x240)
LCM = 178545254400/480
LCM = 371969280
Thus, we can understand that the LCM of 768,916,940,270 is 371969280.
