Given numbers are 989,410,618,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,410,618,345 is 125296410.
Find LCM of 989,410,618,345 with Prime Factorization
2 | 989, 410, 618, 345 |
3 | 989, 205, 309, 345 |
5 | 989, 205, 103, 115 |
23 | 989, 41, 103, 23 |
43, 41, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 43 x 41 x 103 x 1 = 125296410
Therefore, the lowest common multiple of 989,410,618,345 is 125296410.
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 410 x 618 x 345 = 86454522900
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
410 : 1, 2, 5, 10, 41, 82, 205, 410
618 : 1, 2, 3, 6, 103, 206, 309, 618
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,410,618,345, is 1.
Now, the common factors can be found like this.
989:23x 43
410:2x 5x 41
618:2x 3x 103
345:3x 5x 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 3x 5x 23 = 690
Therefore, the value for common factors is 690.
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 = 86454522900/(1x690)
LCM = 86454522900/690
LCM = 125296410
Thus, we can understand that the LCM of 989,410,618,345 is 125296410.
