Given numbers are 209,741,962,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,741,962,639 is 128476062.
Find LCM of 209,741,962,639 with Prime Factorization
3 | 209, 741, 962, 639 |
13 | 209, 247, 962, 213 |
19 | 209, 19, 74, 213 |
11, 1, 74, 213 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 19 x 11 x 1 x 74 x 213 = 128476062
Therefore, the lowest common multiple of 209,741,962,639 is 128476062.
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.
209 x 741 x 962 x 639 = 95200761942
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.
209 : 1, 11, 19, 209
741 : 1, 3, 13, 19, 39, 57, 247, 741
962 : 1, 2, 13, 26, 37, 74, 481, 962
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,741,962,639, is 1.
Now, the common factors can be found like this.
209:11x 19
741:3x 13x 19
962:2x 13x 37
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 19 = 741
Therefore, the value for common factors is 741.
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 = 95200761942/(1x741)
LCM = 95200761942/741
LCM = 128476062
Thus, we can understand that the LCM of 209,741,962,639 is 128476062.
