Given numbers are 209,912,438,659,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,912,438,659,745 is 359544020880.
Find LCM of 209,912,438,659,745 with Prime Factorization
| 2 | 209, 912, 438, 659, 745 |
| 3 | 209, 456, 219, 659, 745 |
| 19 | 209, 152, 73, 659, 745 |
| 11, 8, 73, 659, 745 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 11 x 8 x 73 x 659 x 745 = 359544020880
Therefore, the lowest common multiple of 209,912,438,659,745 is 359544020880.
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 912 x 438 x 659 x 745 = 40988018380320
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
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
438 : 1, 2, 3, 6, 73, 146, 219, 438
659 : 1, 659
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,912,438,659,745, is 1.
Now, the common factors can be found like this.
209:11x 19
912:2x 2x 2x 2x 3x 19
438:2x 3x 73
659:659
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 40988018380320/(1x114)
LCM = 40988018380320/114
LCM = 359544020880
Thus, we can understand that the LCM of 209,912,438,659,745 is 359544020880.
