The LCM of 557,196,980,381 is 207972660.
Find LCM of 557,196,980,381 with Prime Factorization
| 2 | 557, 196, 980, 381 |
| 2 | 557, 98, 490, 381 |
| 7 | 557, 49, 245, 381 |
| 7 | 557, 7, 35, 381 |
| 557, 1, 5, 381 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 557 x 1 x 5 x 381 = 207972660
Therefore, the lowest common multiple of 557,196,980,381 is 207972660.
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.
557 x 196 x 980 x 381 = 40762641360
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.
557 : 1, 557
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,196,980,381, is 1.
Now, the common factors can be found like this.
557:557
196:2x 2x 7x 7
980:2x 2x 5x 7x 7
381:3x 127
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 40762641360/(1x196)
LCM = 40762641360/196
LCM = 207972660
Thus, we can understand that the LCM of 557,196,980,381 is 207972660.
