Given numbers are 220,556,197,871,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,556,197,871,320 is 83954087360.
Find LCM of 220,556,197,871,320 with Prime Factorization
| 2 | 220, 556, 197, 871, 320 |
| 2 | 110, 278, 197, 871, 160 |
| 5 | 55, 139, 197, 871, 80 |
| 11, 139, 197, 871, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 139 x 197 x 871 x 16 = 83954087360
Therefore, the lowest common multiple of 220,556,197,871,320 is 83954087360.
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.
220 x 556 x 197 x 871 x 320 = 6716326988800
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
556 : 1, 2, 4, 139, 278, 556
197 : 1, 197
871 : 1, 13, 67, 871
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,556,197,871,320, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
556:2x 2x 139
197:197
871:13x 67
320:2x 2x 2x 2x 2x 2x 5
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 5 = 80
Therefore, the value for common factors is 80.
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 = 6716326988800/(1x80)
LCM = 6716326988800/80
LCM = 83954087360
Thus, we can understand that the LCM of 220,556,197,871,320 is 83954087360.
