Given numbers are 280,965,748,983
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,965,748,983 is 9933686840.
Find LCM of 280,965,748,983 with Prime Factorization
2 | 280, 965, 748, 983 |
2 | 140, 965, 374, 983 |
5 | 70, 965, 187, 983 |
14, 193, 187, 983 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 14 x 193 x 187 x 983 = 9933686840
Therefore, the lowest common multiple of 280,965,748,983 is 9933686840.
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.
280 x 965 x 748 x 983 = 198673736800
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
965 : 1, 5, 193, 965
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
983 : 1, 983
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,965,748,983, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
965:5x 193
748:2x 2x 11x 17
983:983
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 5 = 20
Therefore, the value for common factors is 20.
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 = 198673736800/(1x20)
LCM = 198673736800/20
LCM = 9933686840
Thus, we can understand that the LCM of 280,965,748,983 is 9933686840.
