Given numbers are 766,245,561,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,245,561,138 is 2421506010.
Find LCM of 766,245,561,138 with Prime Factorization
2 | 766, 245, 561, 138 |
3 | 383, 245, 561, 69 |
383, 245, 187, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 383 x 245 x 187 x 23 = 2421506010
Therefore, the lowest common multiple of 766,245,561,138 is 2421506010.
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.
766 x 245 x 561 x 138 = 14529036060
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.
766 : 1, 2, 383, 766
245 : 1, 5, 7, 35, 49, 245
561 : 1, 3, 11, 17, 33, 51, 187, 561
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,245,561,138, is 1.
Now, the common factors can be found like this.
766:2x 383
245:5x 7x 7
561:3x 11x 17
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 14529036060/(1x6)
LCM = 14529036060/6
LCM = 2421506010
Thus, we can understand that the LCM of 766,245,561,138 is 2421506010.
