Find LCM of 448,922,428,940,720 with Prime Factorization
| 2 | 448, 922, 428, 940, 720 |
| 2 | 224, 461, 214, 470, 360 |
| 2 | 112, 461, 107, 235, 180 |
| 2 | 56, 461, 107, 235, 90 |
| 5 | 28, 461, 107, 235, 45 |
| 28, 461, 107, 47, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 28 x 461 x 107 x 47 x 9 = 46738319040
Therefore, the lowest common multiple of 448,922,428,940,720 is 46738319040.
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.
448 x 922 x 428 x 940 x 720 = 119650096742400
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.
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
922 : 1, 2, 461, 922
428 : 1, 2, 4, 107, 214, 428
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,922,428,940,720, is 2.
Now, the common factors can be found like this.
448:2x 2x 2x 2x 2x 2x 7
922:2x 461
428:2x 2x 107
940:2x 2x 5x 47
720:2x 2x 2x 2x 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 2x 2x 2x 2x 2x 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 119650096742400/(2x1280)
LCM = 119650096742400/2560
LCM = 46738319040
Thus, we can understand that the LCM of 448,922,428,940,720 is 46738319040.
