Find LCM of 665,854,354,562,305 with Prime Factorization
2 | 665, 854, 354, 562, 305 |
5 | 665, 427, 177, 281, 305 |
7 | 133, 427, 177, 281, 61 |
61 | 19, 61, 177, 281, 61 |
19, 1, 177, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 61 x 19 x 1 x 177 x 281 x 1 = 4035162810
Therefore, the lowest common multiple of 665,854,354,562,305 is 4035162810.
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.
665 x 854 x 354 x 562 x 305 = 34460290397400
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
854 : 1, 2, 7, 14, 61, 122, 427, 854
354 : 1, 2, 3, 6, 59, 118, 177, 354
562 : 1, 2, 281, 562
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,854,354,562,305, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
854:2x 7x 61
354:2x 3x 59
562:2x 281
305:5x 61
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 7x 61 = 8540
Therefore, the value for common factors is 8540.
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 = 34460290397400/(1x8540)
LCM = 34460290397400/8540
LCM = 4035162810
Thus, we can understand that the LCM of 665,854,354,562,305 is 4035162810.
