Find LCM of 680,450,605,649,365 with Prime Factorization
2 | 680, 450, 605, 649, 365 |
5 | 340, 225, 605, 649, 365 |
11 | 68, 45, 121, 649, 73 |
68, 45, 11, 59, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 68 x 45 x 11 x 59 x 73 = 15947098200
Therefore, the lowest common multiple of 680,450,605,649,365 is 15947098200.
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.
680 x 450 x 605 x 649 x 365 = 43854520050000
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
605 : 1, 5, 11, 55, 121, 605
649 : 1, 11, 59, 649
365 : 1, 5, 73, 365
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,450,605,649,365, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
450:2x 3x 3x 5x 5
605:5x 11x 11
649:11x 59
365:5x 73
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 5x 5x 11 = 2750
Therefore, the value for common factors is 2750.
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 = 43854520050000/(1x2750)
LCM = 43854520050000/2750
LCM = 15947098200
Thus, we can understand that the LCM of 680,450,605,649,365 is 15947098200.
