Given numbers are 222,972,856,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 222,972,856,768 is 246281472.
Find LCM of 222,972,856,768 with Prime Factorization
| 2 | 222, 972, 856, 768 |
| 2 | 111, 486, 428, 384 |
| 2 | 111, 243, 214, 192 |
| 3 | 111, 243, 107, 96 |
| 37, 81, 107, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 37 x 81 x 107 x 32 = 246281472
Therefore, the lowest common multiple of 222,972,856,768 is 246281472.
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.
222 x 972 x 856 x 768 = 141858127872
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.
222 : 1, 2, 3, 6, 37, 74, 111, 222
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
856 : 1, 2, 4, 8, 107, 214, 428, 856
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,972,856,768, is 2.
Now, the common factors can be found like this.
222:2x 3x 37
972:2x 2x 3x 3x 3x 3x 3
856:2x 2x 2x 107
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 141858127872/(2x288)
LCM = 141858127872/576
LCM = 246281472
Thus, we can understand that the LCM of 222,972,856,768 is 246281472.
