Given numbers are 659,781,836,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 659,781,836,557 is 21787391428.
Find LCM of 659,781,836,557 with Prime Factorization
| 11 | 659, 781, 836, 557 |
| 659, 71, 76, 557 |
Multiply the prime numbers at the bottom and the left side.
11 x 659 x 71 x 76 x 557 = 21787391428
Therefore, the lowest common multiple of 659,781,836,557 is 21787391428.
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.
659 x 781 x 836 x 557 = 239661305708
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.
659 : 1, 659
781 : 1, 11, 71, 781
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 659,781,836,557, is 1.
Now, the common factors can be found like this.
659:659
781:11x 71
836:2x 2x 11x 19
557:557
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 = 239661305708/(1x11)
LCM = 239661305708/11
LCM = 21787391428
Thus, we can understand that the LCM of 659,781,836,557 is 21787391428.
