Given numbers are 278,998,556,975,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,998,556,975,616 is 41658216600.
Find LCM of 278,998,556,975,616 with Prime Factorization
| 2 | 278, 998, 556, 975, 616 |
| 2 | 139, 499, 278, 975, 308 |
| 139 | 139, 499, 139, 975, 154 |
| 1, 499, 1, 975, 154 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 1 x 499 x 1 x 975 x 154 = 41658216600
Therefore, the lowest common multiple of 278,998,556,975,616 is 41658216600.
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.
278 x 998 x 556 x 975 x 616 = 92647873718400
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.
278 : 1, 2, 139, 278
998 : 1, 2, 499, 998
556 : 1, 2, 4, 139, 278, 556
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,998,556,975,616, is 1.
Now, the common factors can be found like this.
278:2x 139
998:2x 499
556:2x 2x 139
975:3x 5x 5x 13
616:2x 2x 2x 7x 11
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 2x 139 = 2224
Therefore, the value for common factors is 2224.
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 = 92647873718400/(1x2224)
LCM = 92647873718400/2224
LCM = 41658216600
Thus, we can understand that the LCM of 278,998,556,975,616 is 41658216600.
