Given numbers are 808,938,399,651,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,938,399,651,661 is 442611009624.
Find LCM of 808,938,399,651,661 with Prime Factorization
| 2 | 808, 938, 399, 651, 661 |
| 3 | 404, 469, 399, 651, 661 |
| 7 | 404, 469, 133, 217, 661 |
| 404, 67, 19, 31, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 404 x 67 x 19 x 31 x 661 = 442611009624
Therefore, the lowest common multiple of 808,938,399,651,661 is 442611009624.
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.
808 x 938 x 399 x 651 x 661 = 130127636829456
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
938 : 1, 2, 7, 14, 67, 134, 469, 938
399 : 1, 3, 7, 19, 21, 57, 133, 399
651 : 1, 3, 7, 21, 31, 93, 217, 651
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,938,399,651,661, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
938:2x 7x 67
399:3x 7x 19
651:3x 7x 31
661:661
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 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 130127636829456/(1x294)
LCM = 130127636829456/294
LCM = 442611009624
Thus, we can understand that the LCM of 808,938,399,651,661 is 442611009624.
