Given numbers are 955,721,618,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 955,721,618,643 is 2656445190.
Find LCM of 955,721,618,643 with Prime Factorization
| 103 | 955, 721, 618, 643 |
| 955, 7, 6, 643 |
Multiply the prime numbers at the bottom and the left side.
103 x 955 x 7 x 6 x 643 = 2656445190
Therefore, the lowest common multiple of 955,721,618,643 is 2656445190.
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.
955 x 721 x 618 x 643 = 273613854570
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.
955 : 1, 5, 191, 955
721 : 1, 7, 103, 721
618 : 1, 2, 3, 6, 103, 206, 309, 618
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,721,618,643, is 1.
Now, the common factors can be found like this.
955:5x 191
721:7x 103
618:2x 3x 103
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
103 = 103
Therefore, the value for common factors is 103.
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 = 273613854570/(1x103)
LCM = 273613854570/103
LCM = 2656445190
Thus, we can understand that the LCM of 955,721,618,643 is 2656445190.
