Given numbers are 800,678,634,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 800,678,634,634 is 85970400.
Find LCM of 800,678,634,634 with Prime Factorization
| 2 | 800, 678, 634, 634 |
| 317 | 400, 339, 317, 317 |
| 400, 339, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 317 x 400 x 339 x 1 x 1 = 85970400
Therefore, the lowest common multiple of 800,678,634,634 is 85970400.
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.
800 x 678 x 634 x 634 = 218020934400
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.
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
678 : 1, 2, 3, 6, 113, 226, 339, 678
634 : 1, 2, 317, 634
634 : 1, 2, 317, 634
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,678,634,634, is 2.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
678:2x 3x 113
634:2x 317
634:2x 317
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 317 = 1268
Therefore, the value for common factors is 1268.
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 = 218020934400/(2x1268)
LCM = 218020934400/2536
LCM = 85970400
Thus, we can understand that the LCM of 800,678,634,634 is 85970400.
