Given numbers are 3926,4420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3926,4420 is 667420.
Find LCM of 3926,4420 with Prime Factorization
| 2 | 3926, 4420 |
| 13 | 1963, 2210 |
| 151, 170 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 151 x 170 = 667420
Therefore, the lowest common multiple of 3926,4420 is 667420.
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.
3926 x 4420 = 17352920
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.
3926 : 1, 2, 13, 26, 151, 302, 1963, 3926
4420 : 1, 2, 4, 5, 10, 13, 17, 20, 26, 34, 52, 65, 68, 85, 130, 170, 221, 260, 340, 442, 884, 1105, 2210, 4420
26 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3926,4420, is 26.
Now, the common factors can be found like this.
3926:2x 13x 151
4420:2x 2x 5x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 17352920/(26x1)
LCM = 17352920/26
LCM = 667420
Thus, we can understand that the LCM of 3926,4420 is 667420.
