Find LCM of 247,361,777,620,105 with Prime Factorization
3 | 247, 361, 777, 620, 105 |
5 | 247, 361, 259, 620, 35 |
7 | 247, 361, 259, 124, 7 |
19 | 247, 361, 37, 124, 1 |
13, 19, 37, 124, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 19 x 13 x 19 x 37 x 124 x 1 = 2260805820
Therefore, the lowest common multiple of 247,361,777,620,105 is 2260805820.
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.
247 x 361 x 777 x 620 x 105 = 4510307610900
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.
247 : 1, 13, 19, 247
361 : 1, 19, 361
777 : 1, 3, 7, 21, 37, 111, 259, 777
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,361,777,620,105, is 1.
Now, the common factors can be found like this.
247:13x 19
361:19x 19
777:3x 7x 37
620:2x 2x 5x 31
105:3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 19 = 1995
Therefore, the value for common factors is 1995.
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 = 4510307610900/(1x1995)
LCM = 4510307610900/1995
LCM = 2260805820
Thus, we can understand that the LCM of 247,361,777,620,105 is 2260805820.
