Given numbers are 731,302,663,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,302,663,942 is 1351725726.
Find LCM of 731,302,663,942 with Prime Factorization
| 2 | 731, 302, 663, 942 |
| 3 | 731, 151, 663, 471 |
| 17 | 731, 151, 221, 157 |
| 43, 151, 13, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 43 x 151 x 13 x 157 = 1351725726
Therefore, the lowest common multiple of 731,302,663,942 is 1351725726.
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.
731 x 302 x 663 x 942 = 137876024052
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.
731 : 1, 17, 43, 731
302 : 1, 2, 151, 302
663 : 1, 3, 13, 17, 39, 51, 221, 663
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,302,663,942, is 1.
Now, the common factors can be found like this.
731:17x 43
302:2x 151
663:3x 13x 17
942:2x 3x 157
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 17 = 102
Therefore, the value for common factors is 102.
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 = 137876024052/(1x102)
LCM = 137876024052/102
LCM = 1351725726
Thus, we can understand that the LCM of 731,302,663,942 is 1351725726.
