Given numbers are 781,702,538,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,702,538,356 is 26251881084.
Find LCM of 781,702,538,356 with Prime Factorization
2 | 781, 702, 538, 356 |
781, 351, 269, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 781 x 351 x 269 x 178 = 26251881084
Therefore, the lowest common multiple of 781,702,538,356 is 26251881084.
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 702 x 538 x 356 = 105007524336
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
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
538 : 1, 2, 269, 538
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,702,538,356, is 1.
Now, the common factors can be found like this.
781:11x 71
702:2x 3x 3x 3x 13
538:2x 269
356:2x 2x 89
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 = 105007524336/(1x4)
LCM = 105007524336/4
LCM = 26251881084
Thus, we can understand that the LCM of 781,702,538,356 is 26251881084.
