Find LCM of 475,480,420,484 with Prime Factorization
2 | 475, 480, 420, 484 |
2 | 475, 240, 210, 242 |
3 | 475, 120, 105, 121 |
5 | 475, 40, 35, 121 |
95, 8, 7, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 95 x 8 x 7 x 121 = 38623200
Therefore, the lowest common multiple of 475,480,420,484 is 38623200.
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.
475 x 480 x 420 x 484 = 46347840000
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.
475 : 1, 5, 19, 25, 95, 475
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
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,480,420,484, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
480:2x 2x 2x 2x 2x 3x 5
420:2x 2x 3x 5x 7
484:2x 2x 11x 11
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 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 46347840000/(1x1200)
LCM = 46347840000/1200
LCM = 38623200
Thus, we can understand that the LCM of 475,480,420,484 is 38623200.
