Given numbers are 445,209,946,697,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,209,946,697,394 is 1098256424870.
Find LCM of 445,209,946,697,394 with Prime Factorization
| 2 | 445, 209, 946, 697, 394 |
| 11 | 445, 209, 473, 697, 197 |
| 445, 19, 43, 697, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 445 x 19 x 43 x 697 x 197 = 1098256424870
Therefore, the lowest common multiple of 445,209,946,697,394 is 1098256424870.
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.
445 x 209 x 946 x 697 x 394 = 24161641347140
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.
445 : 1, 5, 89, 445
209 : 1, 11, 19, 209
946 : 1, 2, 11, 22, 43, 86, 473, 946
697 : 1, 17, 41, 697
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,209,946,697,394, is 1.
Now, the common factors can be found like this.
445:5x 89
209:11x 19
946:2x 11x 43
697:17x 41
394:2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 24161641347140/(1x22)
LCM = 24161641347140/22
LCM = 1098256424870
Thus, we can understand that the LCM of 445,209,946,697,394 is 1098256424870.
