Given numbers are 991,279,654,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,279,654,109 is 60274602.
Find LCM of 991,279,654,109 with Prime Factorization
3 | 991, 279, 654, 109 |
109 | 991, 93, 218, 109 |
991, 93, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 109 x 991 x 93 x 2 x 1 = 60274602
Therefore, the lowest common multiple of 991,279,654,109 is 60274602.
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.
991 x 279 x 654 x 109 = 19709794854
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.
991 : 1, 991
279 : 1, 3, 9, 31, 93, 279
654 : 1, 2, 3, 6, 109, 218, 327, 654
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,279,654,109, is 1.
Now, the common factors can be found like this.
991:991
279:3x 3x 31
654:2x 3x 109
109:109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 109 = 327
Therefore, the value for common factors is 327.
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 = 19709794854/(1x327)
LCM = 19709794854/327
LCM = 60274602
Thus, we can understand that the LCM of 991,279,654,109 is 60274602.
