Given numbers are 103,538,380,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,538,380,618 is 31585980.
Find LCM of 103,538,380,618 with Prime Factorization
2 | 103, 538, 380, 618 |
103 | 103, 269, 190, 309 |
1, 269, 190, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 103 x 1 x 269 x 190 x 3 = 31585980
Therefore, the lowest common multiple of 103,538,380,618 is 31585980.
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.
103 x 538 x 380 x 618 = 13013423760
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.
103 : 1, 103
538 : 1, 2, 269, 538
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,538,380,618, is 1.
Now, the common factors can be found like this.
103:103
538:2x 269
380:2x 2x 5x 19
618:2x 3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 103 = 412
Therefore, the value for common factors is 412.
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 = 13013423760/(1x412)
LCM = 13013423760/412
LCM = 31585980
Thus, we can understand that the LCM of 103,538,380,618 is 31585980.
