Given numbers are 807,231,942,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,231,942,748 is 663395964.
Find LCM of 807,231,942,748 with Prime Factorization
| 2 | 807, 231, 942, 748 |
| 3 | 807, 231, 471, 374 |
| 11 | 269, 77, 157, 374 |
| 269, 7, 157, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 269 x 7 x 157 x 34 = 663395964
Therefore, the lowest common multiple of 807,231,942,748 is 663395964.
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.
807 x 231 x 942 x 748 = 131352400872
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.
807 : 1, 3, 269, 807
231 : 1, 3, 7, 11, 21, 33, 77, 231
942 : 1, 2, 3, 6, 157, 314, 471, 942
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,231,942,748, is 1.
Now, the common factors can be found like this.
807:3x 269
231:3x 7x 11
942:2x 3x 157
748:2x 2x 11x 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 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 131352400872/(1x198)
LCM = 131352400872/198
LCM = 663395964
Thus, we can understand that the LCM of 807,231,942,748 is 663395964.
