Given numbers are 367,781,642,294,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 367,781,642,294,831 is 2497629269982.
Find LCM of 367,781,642,294,831 with Prime Factorization
| 2 | 367, 781, 642, 294, 831 |
| 3 | 367, 781, 321, 147, 831 |
| 367, 781, 107, 49, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 367 x 781 x 107 x 49 x 277 = 2497629269982
Therefore, the lowest common multiple of 367,781,642,294,831 is 2497629269982.
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.
367 x 781 x 642 x 294 x 831 = 44957326859676
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.
367 : 1, 367
781 : 1, 11, 71, 781
642 : 1, 2, 3, 6, 107, 214, 321, 642
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 367,781,642,294,831, is 1.
Now, the common factors can be found like this.
367:367
781:11x 71
642:2x 3x 107
294:2x 3x 7x 7
831:3x 277
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 3 = 18
Therefore, the value for common factors is 18.
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 = 44957326859676/(1x18)
LCM = 44957326859676/18
LCM = 2497629269982
Thus, we can understand that the LCM of 367,781,642,294,831 is 2497629269982.
