Given numbers are 243,391,706,991,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 243,391,706,991,618 is 6846972935994.
Find LCM of 243,391,706,991,618 with Prime Factorization
2 | 243, 391, 706, 991, 618 |
3 | 243, 391, 353, 991, 309 |
81, 391, 353, 991, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 81 x 391 x 353 x 991 x 103 = 6846972935994
Therefore, the lowest common multiple of 243,391,706,991,618 is 6846972935994.
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.
243 x 391 x 706 x 991 x 618 = 41081837615964
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.
243 : 1, 3, 9, 27, 81, 243
391 : 1, 17, 23, 391
706 : 1, 2, 353, 706
991 : 1, 991
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 243,391,706,991,618, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
391:17x 23
706:2x 353
991:991
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 3 = 6
Therefore, the value for common factors is 6.
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 = 41081837615964/(1x6)
LCM = 41081837615964/6
LCM = 6846972935994
Thus, we can understand that the LCM of 243,391,706,991,618 is 6846972935994.
