Given numbers are 688,299,221,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,299,221,255 is 52456560.
Find LCM of 688,299,221,255 with Prime Factorization
13 | 688, 299, 221, 255 |
17 | 688, 23, 17, 255 |
688, 23, 1, 15 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 688 x 23 x 1 x 15 = 52456560
Therefore, the lowest common multiple of 688,299,221,255 is 52456560.
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.
688 x 299 x 221 x 255 = 11592899760
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
299 : 1, 13, 23, 299
221 : 1, 13, 17, 221
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,299,221,255, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
299:13x 23
221:13x 17
255:3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 11592899760/(1x221)
LCM = 11592899760/221
LCM = 52456560
Thus, we can understand that the LCM of 688,299,221,255 is 52456560.
