Given numbers are 575,697,575,966,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 575,697,575,966,821 is 13819523550.
Find LCM of 575,697,575,966,821 with Prime Factorization
| 5 | 575, 697, 575, 966, 821 |
| 5 | 115, 697, 115, 966, 821 |
| 23 | 23, 697, 23, 966, 821 |
| 1, 697, 1, 42, 821 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 23 x 1 x 697 x 1 x 42 x 821 = 13819523550
Therefore, the lowest common multiple of 575,697,575,966,821 is 13819523550.
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.
575 x 697 x 575 x 966 x 821 = 182763198948750
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.
575 : 1, 5, 23, 25, 115, 575
697 : 1, 17, 41, 697
575 : 1, 5, 23, 25, 115, 575
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 575,697,575,966,821, is 1.
Now, the common factors can be found like this.
575:5x 5x 23
697:17x 41
575:5x 5x 23
966:2x 3x 7x 23
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 23x 23 = 13225
Therefore, the value for common factors is 13225.
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 = 182763198948750/(1x13225)
LCM = 182763198948750/13225
LCM = 13819523550
Thus, we can understand that the LCM of 575,697,575,966,821 is 13819523550.
