Given numbers are 430,428,921,989,322
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 430,428,921,989,322 is 13644817620.
Find LCM of 430,428,921,989,322 with Prime Factorization
| 2 | 430, 428, 921, 989, 322 |
| 23 | 215, 214, 921, 989, 161 |
| 43 | 215, 214, 921, 43, 7 |
| 5, 214, 921, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 43 x 5 x 214 x 921 x 1 x 7 = 13644817620
Therefore, the lowest common multiple of 430,428,921,989,322 is 13644817620.
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.
430 x 428 x 921 x 989 x 322 = 53978898504720
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
428 : 1, 2, 4, 107, 214, 428
921 : 1, 3, 307, 921
989 : 1, 23, 43, 989
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,428,921,989,322, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
428:2x 2x 107
921:3x 307
989:23x 43
322:2x 7x 23
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 23x 43 = 3956
Therefore, the value for common factors is 3956.
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 = 53978898504720/(1x3956)
LCM = 53978898504720/3956
LCM = 13644817620
Thus, we can understand that the LCM of 430,428,921,989,322 is 13644817620.
