Given numbers are 938,515,865,930,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 938,515,865,930,811 is 6303183829530.
Find LCM of 938,515,865,930,811 with Prime Factorization
| 2 | 938, 515, 865, 930, 811 |
| 5 | 469, 515, 865, 465, 811 |
| 469, 103, 173, 93, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 469 x 103 x 173 x 93 x 811 = 6303183829530
Therefore, the lowest common multiple of 938,515,865,930,811 is 6303183829530.
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.
938 x 515 x 865 x 930 x 811 = 315159191476500
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.
938 : 1, 2, 7, 14, 67, 134, 469, 938
515 : 1, 5, 103, 515
865 : 1, 5, 173, 865
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,515,865,930,811, is 1.
Now, the common factors can be found like this.
938:2x 7x 67
515:5x 103
865:5x 173
930:2x 3x 5x 31
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 315159191476500/(1x50)
LCM = 315159191476500/50
LCM = 6303183829530
Thus, we can understand that the LCM of 938,515,865,930,811 is 6303183829530.
