Given numbers are 424,342,618,518,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,342,618,518,861 is 79301757528.
Find LCM of 424,342,618,518,861 with Prime Factorization
| 2 | 424, 342, 618, 518, 861 |
| 3 | 212, 171, 309, 259, 861 |
| 7 | 212, 57, 103, 259, 287 |
| 212, 57, 103, 37, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 212 x 57 x 103 x 37 x 41 = 79301757528
Therefore, the lowest common multiple of 424,342,618,518,861 is 79301757528.
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.
424 x 342 x 618 x 518 x 861 = 39968085794112
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
618 : 1, 2, 3, 6, 103, 206, 309, 618
518 : 1, 2, 7, 14, 37, 74, 259, 518
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,342,618,518,861, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
342:2x 3x 3x 19
618:2x 3x 103
518:2x 7x 37
861:3x 7x 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 2x 2x 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 39968085794112/(1x504)
LCM = 39968085794112/504
LCM = 79301757528
Thus, we can understand that the LCM of 424,342,618,518,861 is 79301757528.
