Find LCM of 662,561,173,909,459 with Prime Factorization
| 3 | 662, 561, 173, 909, 459 |
| 3 | 662, 187, 173, 303, 153 |
| 17 | 662, 187, 173, 101, 51 |
| 662, 11, 173, 101, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 662 x 11 x 173 x 101 x 3 = 58402419174
Therefore, the lowest common multiple of 662,561,173,909,459 is 58402419174.
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.
662 x 561 x 173 x 909 x 459 = 26806710400866
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.
662 : 1, 2, 331, 662
561 : 1, 3, 11, 17, 33, 51, 187, 561
173 : 1, 173
909 : 1, 3, 9, 101, 303, 909
459 : 1, 3, 9, 17, 27, 51, 153, 459
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,561,173,909,459, is 1.
Now, the common factors can be found like this.
662:2x 331
561:3x 11x 17
173:173
909:3x 3x 101
459:3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 26806710400866/(1x459)
LCM = 26806710400866/459
LCM = 58402419174
Thus, we can understand that the LCM of 662,561,173,909,459 is 58402419174.
