Given numbers are 398,450,899,510,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,450,899,510,688 is 470795871600.
Find LCM of 398,450,899,510,688 with Prime Factorization
| 2 | 398, 450, 899, 510, 688 |
| 3 | 199, 225, 899, 255, 344 |
| 5 | 199, 75, 899, 85, 344 |
| 199, 15, 899, 17, 344 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 199 x 15 x 899 x 17 x 344 = 470795871600
Therefore, the lowest common multiple of 398,450,899,510,688 is 470795871600.
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.
398 x 450 x 899 x 510 x 688 = 56495504592000
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.
398 : 1, 2, 199, 398
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
899 : 1, 29, 31, 899
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,450,899,510,688, is 1.
Now, the common factors can be found like this.
398:2x 199
450:2x 3x 3x 5x 5
899:29x 31
510:2x 3x 5x 17
688:2x 2x 2x 2x 43
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 = 56495504592000/(1x120)
LCM = 56495504592000/120
LCM = 470795871600
Thus, we can understand that the LCM of 398,450,899,510,688 is 470795871600.
