Find LCM of 420,924,263,260 with Prime Factorization
| 2 | 420, 924, 263, 260 |
| 2 | 210, 462, 263, 130 |
| 3 | 105, 231, 263, 65 |
| 5 | 35, 77, 263, 65 |
| 7 | 7, 77, 263, 13 |
| 1, 11, 263, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 1 x 11 x 263 x 13 = 15795780
Therefore, the lowest common multiple of 420,924,263,260 is 15795780.
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.
420 x 924 x 263 x 260 = 26536910400
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.
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
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
263 : 1, 263
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,924,263,260, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
924:2x 2x 3x 7x 11
263:263
260:2x 2x 5x 13
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 7 = 1680
Therefore, the value for common factors is 1680.
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 = 26536910400/(1x1680)
LCM = 26536910400/1680
LCM = 15795780
Thus, we can understand that the LCM of 420,924,263,260 is 15795780.
