Given numbers are 618,402,400,455,734
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 618,402,400,455,734 is 276567236400.
Find LCM of 618,402,400,455,734 with Prime Factorization
| 2 | 618, 402, 400, 455, 734 |
| 3 | 309, 201, 200, 455, 367 |
| 5 | 103, 67, 200, 455, 367 |
| 103, 67, 40, 91, 367 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 103 x 67 x 40 x 91 x 367 = 276567236400
Therefore, the lowest common multiple of 618,402,400,455,734 is 276567236400.
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.
618 x 402 x 400 x 455 x 734 = 33188068368000
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
402 : 1, 2, 3, 6, 67, 134, 201, 402
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
455 : 1, 5, 7, 13, 35, 65, 91, 455
734 : 1, 2, 367, 734
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,402,400,455,734, is 1.
Now, the common factors can be found like this.
618:2x 3x 103
402:2x 3x 67
400:2x 2x 2x 2x 5x 5
455:5x 7x 13
734:2x 367
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 33188068368000/(1x120)
LCM = 33188068368000/120
LCM = 276567236400
Thus, we can understand that the LCM of 618,402,400,455,734 is 276567236400.
