Find LCM of 400,661,300,319,293 with Prime Factorization
| 2 | 400, 661, 300, 319, 293 |
| 2 | 200, 661, 150, 319, 293 |
| 5 | 100, 661, 75, 319, 293 |
| 5 | 20, 661, 15, 319, 293 |
| 4, 661, 3, 319, 293 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 4 x 661 x 3 x 319 x 293 = 74138024400
Therefore, the lowest common multiple of 400,661,300,319,293 is 74138024400.
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 661 x 300 x 319 x 293 = 7413802440000
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
661 : 1, 661
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
319 : 1, 11, 29, 319
293 : 1, 293
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,661,300,319,293, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
661:661
300:2x 2x 3x 5x 5
319:11x 29
293:293
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 7413802440000/(1x100)
LCM = 7413802440000/100
LCM = 74138024400
Thus, we can understand that the LCM of 400,661,300,319,293 is 74138024400.
