Given numbers are 538,208,561,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,208,561,974 is 15286478064.
Find LCM of 538,208,561,974 with Prime Factorization
2 | 538, 208, 561, 974 |
269, 104, 561, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 269 x 104 x 561 x 487 = 15286478064
Therefore, the lowest common multiple of 538,208,561,974 is 15286478064.
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.
538 x 208 x 561 x 974 = 61145912256
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.
538 : 1, 2, 269, 538
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
561 : 1, 3, 11, 17, 33, 51, 187, 561
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,208,561,974, is 1.
Now, the common factors can be found like this.
538:2x 269
208:2x 2x 2x 2x 13
561:3x 11x 17
974:2x 487
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 61145912256/(1x4)
LCM = 61145912256/4
LCM = 15286478064
Thus, we can understand that the LCM of 538,208,561,974 is 15286478064.
