The LCM of 294,557,505,980 is 165395580.
Find LCM of 294,557,505,980 with Prime Factorization
| 2 | 294, 557, 505, 980 |
| 5 | 147, 557, 505, 490 |
| 7 | 147, 557, 101, 98 |
| 7 | 21, 557, 101, 14 |
| 3, 557, 101, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 3 x 557 x 101 x 2 = 165395580
Therefore, the lowest common multiple of 294,557,505,980 is 165395580.
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.
294 x 557 x 505 x 980 = 81043834200
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.
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
557 : 1, 557
505 : 1, 5, 101, 505
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 294,557,505,980, is 1.
Now, the common factors can be found like this.
294:2x 3x 7x 7
557:557
505:5x 101
980:2x 2x 5x 7x 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 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 81043834200/(1x490)
LCM = 81043834200/490
LCM = 165395580
Thus, we can understand that the LCM of 294,557,505,980 is 165395580.
