Given numbers are 615,538,693,764,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,538,693,764,418 is 554735980260.
Find LCM of 615,538,693,764,418 with Prime Factorization
2 | 615, 538, 693, 764, 418 |
3 | 615, 269, 693, 382, 209 |
11 | 205, 269, 231, 382, 209 |
205, 269, 21, 382, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 205 x 269 x 21 x 382 x 19 = 554735980260
Therefore, the lowest common multiple of 615,538,693,764,418 is 554735980260.
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.
615 x 538 x 693 x 764 x 418 = 73225149394320
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
538 : 1, 2, 269, 538
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
764 : 1, 2, 4, 191, 382, 764
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,538,693,764,418, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
538:2x 269
693:3x 3x 7x 11
764:2x 2x 191
418:2x 11x 19
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 73225149394320/(1x132)
LCM = 73225149394320/132
LCM = 554735980260
Thus, we can understand that the LCM of 615,538,693,764,418 is 554735980260.
