Given numbers are 902,890,909,243,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,890,909,243,618 is 1014685421310.
Find LCM of 902,890,909,243,618 with Prime Factorization
| 2 | 902, 890, 909, 243, 618 |
| 3 | 451, 445, 909, 243, 309 |
| 3 | 451, 445, 303, 81, 103 |
| 451, 445, 101, 27, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 451 x 445 x 101 x 27 x 103 = 1014685421310
Therefore, the lowest common multiple of 902,890,909,243,618 is 1014685421310.
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.
902 x 890 x 909 x 243 x 618 = 109586025501480
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
890 : 1, 2, 5, 10, 89, 178, 445, 890
909 : 1, 3, 9, 101, 303, 909
243 : 1, 3, 9, 27, 81, 243
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,890,909,243,618, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
890:2x 5x 89
909:3x 3x 101
243:3x 3x 3x 3x 3
618:2x 3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 109586025501480/(1x108)
LCM = 109586025501480/108
LCM = 1014685421310
Thus, we can understand that the LCM of 902,890,909,243,618 is 1014685421310.
