Given numbers are 86,77,49,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 86,77,49,668 is 15482236.
Find LCM of 86,77,49,668 with Prime Factorization
2 | 86, 77, 49, 668 |
7 | 43, 77, 49, 334 |
43, 11, 7, 334 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 43 x 11 x 7 x 334 = 15482236
Therefore, the lowest common multiple of 86,77,49,668 is 15482236.
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.
86 x 77 x 49 x 668 = 216751304
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.
86 : 1, 2, 43, 86
77 : 1, 7, 11, 77
49 : 1, 7, 49
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 86,77,49,668, is 1.
Now, the common factors can be found like this.
86:2x 43
77:7x 11
49:7x 7
668:2x 2x 167
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 216751304/(1x14)
LCM = 216751304/14
LCM = 15482236
Thus, we can understand that the LCM of 86,77,49,668 is 15482236.
