Given numbers are 263,128,972,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 263,128,972,961 is 7861318272.
Find LCM of 263,128,972,961 with Prime Factorization
| 2 | 263, 128, 972, 961 |
| 2 | 263, 64, 486, 961 |
| 263, 32, 243, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 263 x 32 x 243 x 961 = 7861318272
Therefore, the lowest common multiple of 263,128,972,961 is 7861318272.
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.
263 x 128 x 972 x 961 = 31445273088
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.
263 : 1, 263
128 : 1, 2, 4, 8, 16, 32, 64, 128
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,128,972,961, is 1.
Now, the common factors can be found like this.
263:263
128:2x 2x 2x 2x 2x 2x 2
972:2x 2x 3x 3x 3x 3x 3
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 31445273088/(1x4)
LCM = 31445273088/4
LCM = 7861318272
Thus, we can understand that the LCM of 263,128,972,961 is 7861318272.
