Find LCM of 978,722,123,615,117 with Prime Factorization
2 | 978, 722, 123, 615, 117 |
3 | 489, 361, 123, 615, 117 |
41 | 163, 361, 41, 205, 39 |
163, 361, 1, 5, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 163 x 361 x 1 x 5 x 39 = 2822698710
Therefore, the lowest common multiple of 978,722,123,615,117 is 2822698710.
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.
978 x 722 x 123 x 615 x 117 = 6249454943940
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
722 : 1, 2, 19, 38, 361, 722
123 : 1, 3, 41, 123
615 : 1, 3, 5, 15, 41, 123, 205, 615
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,722,123,615,117, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
722:2x 19x 19
123:3x 41
615:3x 5x 41
117:3x 3x 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 3x 3x 3x 41 = 2214
Therefore, the value for common factors is 2214.
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 = 6249454943940/(1x2214)
LCM = 6249454943940/2214
LCM = 2822698710
Thus, we can understand that the LCM of 978,722,123,615,117 is 2822698710.
