Given numbers are 461,667,931,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 461,667,931,686 is 4007785558.
Find LCM of 461,667,931,686 with Prime Factorization
| 7 | 461, 667, 931, 686 |
| 7 | 461, 667, 133, 98 |
| 461, 667, 19, 14 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 461 x 667 x 19 x 14 = 4007785558
Therefore, the lowest common multiple of 461,667,931,686 is 4007785558.
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.
461 x 667 x 931 x 686 = 196381492342
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.
461 : 1, 461
667 : 1, 23, 29, 667
931 : 1, 7, 19, 49, 133, 931
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,667,931,686, is 1.
Now, the common factors can be found like this.
461:461
667:23x 29
931:7x 7x 19
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 196381492342/(1x49)
LCM = 196381492342/49
LCM = 4007785558
Thus, we can understand that the LCM of 461,667,931,686 is 4007785558.
