The LCM of 263,942,561,154 is 324299514.
Find LCM of 263,942,561,154 with Prime Factorization
| 2 | 263, 942, 561, 154 |
| 3 | 263, 471, 561, 77 |
| 11 | 263, 157, 187, 77 |
| 263, 157, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 263 x 157 x 17 x 7 = 324299514
Therefore, the lowest common multiple of 263,942,561,154 is 324299514.
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 942 x 561 x 154 = 21403767924
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
942 : 1, 2, 3, 6, 157, 314, 471, 942
561 : 1, 3, 11, 17, 33, 51, 187, 561
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,942,561,154, is 1.
Now, the common factors can be found like this.
263:263
942:2x 3x 157
561:3x 11x 17
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 21403767924/(1x66)
LCM = 21403767924/66
LCM = 324299514
Thus, we can understand that the LCM of 263,942,561,154 is 324299514.
