Given numbers are 283,781,639,737
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 283,781,639,737 is 133276869.
Find LCM of 283,781,639,737 with Prime Factorization
| 11 | 283, 781, 639, 737 |
| 71 | 283, 71, 639, 67 |
| 283, 1, 9, 67 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 283 x 1 x 9 x 67 = 133276869
Therefore, the lowest common multiple of 283,781,639,737 is 133276869.
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.
283 x 781 x 639 x 737 = 104089234689
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.
283 : 1, 283
781 : 1, 11, 71, 781
639 : 1, 3, 9, 71, 213, 639
737 : 1, 11, 67, 737
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 283,781,639,737, is 1.
Now, the common factors can be found like this.
283:283
781:11x 71
639:3x 3x 71
737:11x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 71 = 781
Therefore, the value for common factors is 781.
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 = 104089234689/(1x781)
LCM = 104089234689/781
LCM = 133276869
Thus, we can understand that the LCM of 283,781,639,737 is 133276869.
