Given numbers are 838,847,661,781,919
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,847,661,781,919 is 30612778457954.
Find LCM of 838,847,661,781,919 with Prime Factorization
11 | 838, 847, 661, 781, 919 |
838, 77, 661, 71, 919 |
Multiply the prime numbers at the bottom and the left side.
11 x 838 x 77 x 661 x 71 x 919 = 30612778457954
Therefore, the lowest common multiple of 838,847,661,781,919 is 30612778457954.
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.
838 x 847 x 661 x 781 x 919 = 336740563037494
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.
838 : 1, 2, 419, 838
847 : 1, 7, 11, 77, 121, 847
661 : 1, 661
781 : 1, 11, 71, 781
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,847,661,781,919, is 1.
Now, the common factors can be found like this.
838:2x 419
847:7x 11x 11
661:661
781:11x 71
919:919
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 336740563037494/(1x11)
LCM = 336740563037494/11
LCM = 30612778457954
Thus, we can understand that the LCM of 838,847,661,781,919 is 30612778457954.
