The LCM of 120,389,615,203,212 is 20591434920.
Find LCM of 120,389,615,203,212 with Prime Factorization
2 | 120, 389, 615, 203, 212 |
2 | 60, 389, 615, 203, 106 |
3 | 30, 389, 615, 203, 53 |
5 | 10, 389, 205, 203, 53 |
2, 389, 41, 203, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 2 x 389 x 41 x 203 x 53 = 20591434920
Therefore, the lowest common multiple of 120,389,615,203,212 is 20591434920.
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.
120 x 389 x 615 x 203 x 212 = 1235486095200
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
389 : 1, 389
615 : 1, 3, 5, 15, 41, 123, 205, 615
203 : 1, 7, 29, 203
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,389,615,203,212, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
389:389
615:3x 5x 41
203:7x 29
212:2x 2x 53
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 1235486095200/(1x60)
LCM = 1235486095200/60
LCM = 20591434920
Thus, we can understand that the LCM of 120,389,615,203,212 is 20591434920.
