Given numbers are 722,400,310,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,400,310,403 is 58193200.
Find LCM of 722,400,310,403 with Prime Factorization
| 2 | 722, 400, 310, 403 |
| 5 | 361, 200, 155, 403 |
| 31 | 361, 40, 31, 403 |
| 361, 40, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 361 x 40 x 1 x 13 = 58193200
Therefore, the lowest common multiple of 722,400,310,403 is 58193200.
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.
722 x 400 x 310 x 403 = 36079784000
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.
722 : 1, 2, 19, 38, 361, 722
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
310 : 1, 2, 5, 10, 31, 62, 155, 310
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,400,310,403, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
400:2x 2x 2x 2x 5x 5
310:2x 5x 31
403:13x 31
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 31 = 620
Therefore, the value for common factors is 620.
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 = 36079784000/(1x620)
LCM = 36079784000/620
LCM = 58193200
Thus, we can understand that the LCM of 722,400,310,403 is 58193200.
