Given numbers are 697,430,425,442,208
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,430,425,442,208 is 155849200.
Find LCM of 697,430,425,442,208 with Prime Factorization
| 2 | 697, 430, 425, 442, 208 |
| 5 | 697, 215, 425, 221, 104 |
| 13 | 697, 43, 85, 221, 104 |
| 17 | 697, 43, 85, 17, 8 |
| 41, 43, 5, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 17 x 41 x 43 x 5 x 1 x 8 = 155849200
Therefore, the lowest common multiple of 697,430,425,442,208 is 155849200.
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 430 x 425 x 442 x 208 = 11710508888000
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
430 : 1, 2, 5, 10, 43, 86, 215, 430
425 : 1, 5, 17, 25, 85, 425
442 : 1, 2, 13, 17, 26, 34, 221, 442
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,430,425,442,208, is 1.
Now, the common factors can be found like this.
697:17x 41
430:2x 5x 43
425:5x 5x 17
442:2x 13x 17
208:2x 2x 2x 2x 13
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 5x 13x 17x 17 = 75140
Therefore, the value for common factors is 75140.
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 = 11710508888000/(1x75140)
LCM = 11710508888000/75140
LCM = 155849200
Thus, we can understand that the LCM of 697,430,425,442,208 is 155849200.
