Find LCM of 782,845,440,868,469 with Prime Factorization
| 2 | 782, 845, 440, 868, 469 |
| 2 | 391, 845, 220, 434, 469 |
| 5 | 391, 845, 110, 217, 469 |
| 7 | 391, 169, 22, 217, 469 |
| 391, 169, 22, 31, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 391 x 169 x 22 x 31 x 67 = 422717935640
Therefore, the lowest common multiple of 782,845,440,868,469 is 422717935640.
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.
782 x 845 x 440 x 868 x 469 = 118361021979200
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
845 : 1, 5, 13, 65, 169, 845
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,845,440,868,469, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
845:5x 13x 13
440:2x 2x 2x 5x 11
868:2x 2x 7x 31
469:7x 67
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 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 118361021979200/(1x280)
LCM = 118361021979200/280
LCM = 422717935640
Thus, we can understand that the LCM of 782,845,440,868,469 is 422717935640.
