Given numbers are 398,665,824,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,665,824,549 is 59865177960.
Find LCM of 398,665,824,549 with Prime Factorization
| 2 | 398, 665, 824, 549 |
| 199, 665, 412, 549 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 665 x 412 x 549 = 59865177960
Therefore, the lowest common multiple of 398,665,824,549 is 59865177960.
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 665 x 824 x 549 = 119730355920
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
665 : 1, 5, 7, 19, 35, 95, 133, 665
824 : 1, 2, 4, 8, 103, 206, 412, 824
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,665,824,549, is 1.
Now, the common factors can be found like this.
398:2x 199
665:5x 7x 19
824:2x 2x 2x 103
549:3x 3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 119730355920/(1x2)
LCM = 119730355920/2
LCM = 59865177960
Thus, we can understand that the LCM of 398,665,824,549 is 59865177960.
