Given numbers are 570,401,821,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,401,821,966 is 30212611170.
Find LCM of 570,401,821,966 with Prime Factorization
| 2 | 570, 401, 821, 966 |
| 3 | 285, 401, 821, 483 |
| 95, 401, 821, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 95 x 401 x 821 x 161 = 30212611170
Therefore, the lowest common multiple of 570,401,821,966 is 30212611170.
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.
570 x 401 x 821 x 966 = 181275667020
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
401 : 1, 401
821 : 1, 821
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,401,821,966, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
401:401
821:821
966:2x 3x 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 3 = 6
Therefore, the value for common factors is 6.
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 = 181275667020/(1x6)
LCM = 181275667020/6
LCM = 30212611170
Thus, we can understand that the LCM of 570,401,821,966 is 30212611170.
