The LCM of 479,168,560,980 is 5633040.
Find LCM of 479,168,560,980 with Prime Factorization
| 2 | 479, 168, 560, 980 |
| 2 | 479, 84, 280, 490 |
| 2 | 479, 42, 140, 245 |
| 5 | 479, 21, 70, 245 |
| 7 | 479, 21, 14, 49 |
| 479, 3, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 479 x 3 x 2 x 7 = 5633040
Therefore, the lowest common multiple of 479,168,560,980 is 5633040.
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.
479 x 168 x 560 x 980 = 44163033600
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.
479 : 1, 479
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
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 479,168,560,980, is 1.
Now, the common factors can be found like this.
479:479
168:2x 2x 2x 3x 7
560:2x 2x 2x 2x 5x 7
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 2x 2x 2x 2x 5x 7x 7 = 7840
Therefore, the value for common factors is 7840.
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 = 44163033600/(1x7840)
LCM = 44163033600/7840
LCM = 5633040
Thus, we can understand that the LCM of 479,168,560,980 is 5633040.
