Given numbers are 238,865,871,990,472
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,865,871,990,472 is 4189463558280.
Find LCM of 238,865,871,990,472 with Prime Factorization
| 2 | 238, 865, 871, 990, 472 |
| 5 | 119, 865, 871, 495, 236 |
| 119, 173, 871, 99, 236 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 119 x 173 x 871 x 99 x 236 = 4189463558280
Therefore, the lowest common multiple of 238,865,871,990,472 is 4189463558280.
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.
238 x 865 x 871 x 990 x 472 = 83789271165600
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
865 : 1, 5, 173, 865
871 : 1, 13, 67, 871
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
472 : 1, 2, 4, 8, 59, 118, 236, 472
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,865,871,990,472, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
865:5x 173
871:13x 67
990:2x 3x 3x 5x 11
472:2x 2x 2x 59
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 5 = 20
Therefore, the value for common factors is 20.
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 = 83789271165600/(1x20)
LCM = 83789271165600/20
LCM = 4189463558280
Thus, we can understand that the LCM of 238,865,871,990,472 is 4189463558280.
