The LCM of 508,381,975,220 is 5448300.
Find LCM of 508,381,975,220 with Prime Factorization
| 2 | 508, 381, 975, 220 |
| 2 | 254, 381, 975, 110 |
| 3 | 127, 381, 975, 55 |
| 5 | 127, 127, 325, 55 |
| 127 | 127, 127, 65, 11 |
| 1, 1, 65, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 127 x 1 x 1 x 65 x 11 = 5448300
Therefore, the lowest common multiple of 508,381,975,220 is 5448300.
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.
508 x 381 x 975 x 220 = 41516046000
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.
508 : 1, 2, 4, 127, 254, 508
381 : 1, 3, 127, 381
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 508,381,975,220, is 1.
Now, the common factors can be found like this.
508:2x 2x 127
381:3x 127
975:3x 5x 5x 13
220:2x 2x 5x 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 3x 5x 127 = 7620
Therefore, the value for common factors is 7620.
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 = 41516046000/(1x7620)
LCM = 41516046000/7620
LCM = 5448300
Thus, we can understand that the LCM of 508,381,975,220 is 5448300.
