The LCM of 400,820,635,576,716 is 13421563200.
Find LCM of 400,820,635,576,716 with Prime Factorization
| 2 | 400, 820, 635, 576, 716 |
| 2 | 200, 410, 635, 288, 358 |
| 2 | 100, 205, 635, 144, 179 |
| 2 | 50, 205, 635, 72, 179 |
| 5 | 25, 205, 635, 36, 179 |
| 5, 41, 127, 36, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 5 x 41 x 127 x 36 x 179 = 13421563200
Therefore, the lowest common multiple of 400,820,635,576,716 is 13421563200.
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.
400 x 820 x 635 x 576 x 716 = 85898004480000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
635 : 1, 5, 127, 635
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
716 : 1, 2, 4, 179, 358, 716
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,820,635,576,716, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
820:2x 2x 5x 41
635:5x 127
576:2x 2x 2x 2x 2x 2x 3x 3
716:2x 2x 179
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 2x 2x 2x 5x 5 = 6400
Therefore, the value for common factors is 6400.
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 = 85898004480000/(1x6400)
LCM = 85898004480000/6400
LCM = 13421563200
Thus, we can understand that the LCM of 400,820,635,576,716 is 13421563200.
