The LCM of 665,604,962,285 is 579595380.
Find LCM of 665,604,962,285 with Prime Factorization
| 2 | 665, 604, 962, 285 |
| 5 | 665, 302, 481, 285 |
| 19 | 133, 302, 481, 57 |
| 7, 302, 481, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 7 x 302 x 481 x 3 = 579595380
Therefore, the lowest common multiple of 665,604,962,285 is 579595380.
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 604 x 962 x 285 = 110123122200
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
604 : 1, 2, 4, 151, 302, 604
962 : 1, 2, 13, 26, 37, 74, 481, 962
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,604,962,285, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
604:2x 2x 151
962:2x 13x 37
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 19 = 190
Therefore, the value for common factors is 190.
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 = 110123122200/(1x190)
LCM = 110123122200/190
LCM = 579595380
Thus, we can understand that the LCM of 665,604,962,285 is 579595380.
