Given numbers are 554,121,980,442,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 554,121,980,442,280 is 14518223720.
Find LCM of 554,121,980,442,280 with Prime Factorization
| 2 | 554, 121, 980, 442, 280 |
| 2 | 277, 121, 490, 221, 140 |
| 5 | 277, 121, 245, 221, 70 |
| 7 | 277, 121, 49, 221, 14 |
| 277, 121, 7, 221, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 277 x 121 x 7 x 221 x 2 = 14518223720
Therefore, the lowest common multiple of 554,121,980,442,280 is 14518223720.
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.
554 x 121 x 980 x 442 x 280 = 8130205283200
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.
554 : 1, 2, 277, 554
121 : 1, 11, 121
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
442 : 1, 2, 13, 17, 26, 34, 221, 442
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,121,980,442,280, is 1.
Now, the common factors can be found like this.
554:2x 277
121:11x 11
980:2x 2x 5x 7x 7
442:2x 13x 17
280:2x 2x 2x 5x 7
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 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 8130205283200/(1x560)
LCM = 8130205283200/560
LCM = 14518223720
Thus, we can understand that the LCM of 554,121,980,442,280 is 14518223720.
