Given numbers are 781,246,533,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,246,533,831 is 691845726.
Find LCM of 781,246,533,831 with Prime Factorization
| 3 | 781, 246, 533, 831 |
| 41 | 781, 82, 533, 277 |
| 781, 2, 13, 277 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 781 x 2 x 13 x 277 = 691845726
Therefore, the lowest common multiple of 781,246,533,831 is 691845726.
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 246 x 533 x 831 = 85097024298
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
246 : 1, 2, 3, 6, 41, 82, 123, 246
533 : 1, 13, 41, 533
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,246,533,831, is 1.
Now, the common factors can be found like this.
781:11x 71
246:2x 3x 41
533:13x 41
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.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 85097024298/(1x123)
LCM = 85097024298/123
LCM = 691845726
Thus, we can understand that the LCM of 781,246,533,831 is 691845726.
