Given numbers are 679,131,861,164,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 679,131,861,164,749 is 4682631156.
Find LCM of 679,131,861,164,749 with Prime Factorization
7 | 679, 131, 861, 164, 749 |
41 | 97, 131, 123, 164, 107 |
97, 131, 3, 4, 107 |
Multiply the prime numbers at the bottom and the left side.
7 x 41 x 97 x 131 x 3 x 4 x 107 = 4682631156
Therefore, the lowest common multiple of 679,131,861,164,749 is 4682631156.
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.
679 x 131 x 861 x 164 x 749 = 9407405992404
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.
679 : 1, 7, 97, 679
131 : 1, 131
861 : 1, 3, 7, 21, 41, 123, 287, 861
164 : 1, 2, 4, 41, 82, 164
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,131,861,164,749, is 1.
Now, the common factors can be found like this.
679:7x 97
131:131
861:3x 7x 41
164:2x 2x 41
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 41 = 2009
Therefore, the value for common factors is 2009.
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 = 9407405992404/(1x2009)
LCM = 9407405992404/2009
LCM = 4682631156
Thus, we can understand that the LCM of 679,131,861,164,749 is 4682631156.
