Given numbers are 989,759,605,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,759,605,788 is 1414487580.
Find LCM of 989,759,605,788 with Prime Factorization
11 | 989, 759, 605, 788 |
23 | 989, 69, 55, 788 |
43, 3, 55, 788 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 43 x 3 x 55 x 788 = 1414487580
Therefore, the lowest common multiple of 989,759,605,788 is 1414487580.
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.
989 x 759 x 605 x 788 = 357865357740
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.
989 : 1, 23, 43, 989
759 : 1, 3, 11, 23, 33, 69, 253, 759
605 : 1, 5, 11, 55, 121, 605
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,759,605,788, is 1.
Now, the common factors can be found like this.
989:23x 43
759:3x 11x 23
605:5x 11x 11
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23 = 253
Therefore, the value for common factors is 253.
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 = 357865357740/(1x253)
LCM = 357865357740/253
LCM = 1414487580
Thus, we can understand that the LCM of 989,759,605,788 is 1414487580.
