Given numbers are 538,781,838,826
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,781,838,826 is 72710542366.
Find LCM of 538,781,838,826 with Prime Factorization
2 | 538, 781, 838, 826 |
269, 781, 419, 413 |
Multiply the prime numbers at the bottom and the left side.
2 x 269 x 781 x 419 x 413 = 72710542366
Therefore, the lowest common multiple of 538,781,838,826 is 72710542366.
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.
538 x 781 x 838 x 826 = 290842169464
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.
538 : 1, 2, 269, 538
781 : 1, 11, 71, 781
838 : 1, 2, 419, 838
826 : 1, 2, 7, 14, 59, 118, 413, 826
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,781,838,826, is 1.
Now, the common factors can be found like this.
538:2x 269
781:11x 71
838:2x 419
826:2x 7x 59
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 = 290842169464/(1x4)
LCM = 290842169464/4
LCM = 72710542366
Thus, we can understand that the LCM of 538,781,838,826 is 72710542366.
