Given numbers are 709,487,171,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,487,171,931 is 2893126257.
Find LCM of 709,487,171,931 with Prime Factorization
| 19 | 709, 487, 171, 931 |
| 709, 487, 9, 49 |
Multiply the prime numbers at the bottom and the left side.
19 x 709 x 487 x 9 x 49 = 2893126257
Therefore, the lowest common multiple of 709,487,171,931 is 2893126257.
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.
709 x 487 x 171 x 931 = 54969398883
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.
709 : 1, 709
487 : 1, 487
171 : 1, 3, 9, 19, 57, 171
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,487,171,931, is 1.
Now, the common factors can be found like this.
709:709
487:487
171:3x 3x 19
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 54969398883/(1x19)
LCM = 54969398883/19
LCM = 2893126257
Thus, we can understand that the LCM of 709,487,171,931 is 2893126257.
