Given numbers are 781,691,243,264
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,691,243,264 is 1049120424.
Find LCM of 781,691,243,264 with Prime Factorization
| 3 | 781, 691, 243, 264 |
| 11 | 781, 691, 81, 88 |
| 71, 691, 81, 8 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 71 x 691 x 81 x 8 = 1049120424
Therefore, the lowest common multiple of 781,691,243,264 is 1049120424.
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.
781 x 691 x 243 x 264 = 34620973992
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.
781 : 1, 11, 71, 781
691 : 1, 691
243 : 1, 3, 9, 27, 81, 243
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,691,243,264, is 1.
Now, the common factors can be found like this.
781:11x 71
691:691
243:3x 3x 3x 3x 3
264:2x 2x 2x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 34620973992/(1x33)
LCM = 34620973992/33
LCM = 1049120424
Thus, we can understand that the LCM of 781,691,243,264 is 1049120424.
