Find LCM of 489,480,420,994,807 with Prime Factorization
2 | 489, 480, 420, 994, 807 |
2 | 489, 240, 210, 497, 807 |
3 | 489, 120, 105, 497, 807 |
5 | 163, 40, 35, 497, 269 |
7 | 163, 8, 7, 497, 269 |
163, 8, 1, 71, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 163 x 8 x 1 x 71 x 269 = 10460140320
Therefore, the lowest common multiple of 489,480,420,994,807 is 10460140320.
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.
489 x 480 x 420 x 994 x 807 = 79078660819200
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.
489 : 1, 3, 163, 489
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
994 : 1, 2, 7, 14, 71, 142, 497, 994
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,480,420,994,807, is 1.
Now, the common factors can be found like this.
489:3x 163
480:2x 2x 2x 2x 2x 3x 5
420:2x 2x 3x 5x 7
994:2x 7x 71
807:3x 269
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 3x 3x 3x 5x 7 = 7560
Therefore, the value for common factors is 7560.
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 = 79078660819200/(1x7560)
LCM = 79078660819200/7560
LCM = 10460140320
Thus, we can understand that the LCM of 489,480,420,994,807 is 10460140320.
