Given numbers are 874,845,612,655,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,845,612,655,615 is 1213793256780.
Find LCM of 874,845,612,655,615 with Prime Factorization
| 2 | 874, 845, 612, 655, 615 |
| 3 | 437, 845, 306, 655, 615 |
| 5 | 437, 845, 102, 655, 205 |
| 437, 169, 102, 131, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 437 x 169 x 102 x 131 x 41 = 1213793256780
Therefore, the lowest common multiple of 874,845,612,655,615 is 1213793256780.
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.
874 x 845 x 612 x 655 x 615 = 182068988517000
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
845 : 1, 5, 13, 65, 169, 845
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
655 : 1, 5, 131, 655
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,845,612,655,615, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
845:5x 13x 13
612:2x 2x 3x 3x 17
655:5x 131
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 182068988517000/(1x150)
LCM = 182068988517000/150
LCM = 1213793256780
Thus, we can understand that the LCM of 874,845,612,655,615 is 1213793256780.
