Find LCM of 665,545,251,582,810 with Prime Factorization
2 | 665, 545, 251, 582, 810 |
3 | 665, 545, 251, 291, 405 |
5 | 665, 545, 251, 97, 135 |
133, 109, 251, 97, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 133 x 109 x 251 x 97 x 27 = 285896351790
Therefore, the lowest common multiple of 665,545,251,582,810 is 285896351790.
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 545 x 251 x 582 x 810 = 42884452768500
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
545 : 1, 5, 109, 545
251 : 1, 251
582 : 1, 2, 3, 6, 97, 194, 291, 582
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,545,251,582,810, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
545:5x 109
251:251
582:2x 3x 97
810:2x 3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 42884452768500/(1x150)
LCM = 42884452768500/150
LCM = 285896351790
Thus, we can understand that the LCM of 665,545,251,582,810 is 285896351790.
