Given numbers are 697,425,897,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,425,897,805 is 109411575.
Find LCM of 697,425,897,805 with Prime Factorization
| 5 | 697, 425, 897, 805 |
| 17 | 697, 85, 897, 161 |
| 23 | 41, 5, 897, 161 |
| 41, 5, 39, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 17 x 23 x 41 x 5 x 39 x 7 = 109411575
Therefore, the lowest common multiple of 697,425,897,805 is 109411575.
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.
697 x 425 x 897 x 805 = 213899629125
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.
697 : 1, 17, 41, 697
425 : 1, 5, 17, 25, 85, 425
897 : 1, 3, 13, 23, 39, 69, 299, 897
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,425,897,805, is 1.
Now, the common factors can be found like this.
697:17x 41
425:5x 5x 17
897:3x 13x 23
805:5x 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.
5x 17x 23 = 1955
Therefore, the value for common factors is 1955.
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 = 213899629125/(1x1955)
LCM = 213899629125/1955
LCM = 109411575
Thus, we can understand that the LCM of 697,425,897,805 is 109411575.
