Given numbers are 661,272,988,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,272,988,738 is 16386782256.
Find LCM of 661,272,988,738 with Prime Factorization
2 | 661, 272, 988, 738 |
2 | 661, 136, 494, 369 |
661, 68, 247, 369 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 661 x 68 x 247 x 369 = 16386782256
Therefore, the lowest common multiple of 661,272,988,738 is 16386782256.
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.
661 x 272 x 988 x 738 = 131094258048
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.
661 : 1, 661
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,272,988,738, is 1.
Now, the common factors can be found like this.
661:661
272:2x 2x 2x 2x 17
988:2x 2x 13x 19
738:2x 3x 3x 41
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 2 = 8
Therefore, the value for common factors is 8.
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 = 131094258048/(1x8)
LCM = 131094258048/8
LCM = 16386782256
Thus, we can understand that the LCM of 661,272,988,738 is 16386782256.
