Given numbers are 209,980,240,324
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,980,240,324 is 66361680.
Find LCM of 209,980,240,324 with Prime Factorization
| 2 | 209, 980, 240, 324 |
| 2 | 209, 490, 120, 162 |
| 3 | 209, 245, 60, 81 |
| 5 | 209, 245, 20, 27 |
| 209, 49, 4, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 209 x 49 x 4 x 27 = 66361680
Therefore, the lowest common multiple of 209,980,240,324 is 66361680.
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 980 x 240 x 324 = 15926803200
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
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,980,240,324, is 1.
Now, the common factors can be found like this.
209:11x 19
980:2x 2x 5x 7x 7
240:2x 2x 2x 2x 3x 5
324:2x 2x 3x 3x 3x 3
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 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 15926803200/(1x240)
LCM = 15926803200/240
LCM = 66361680
Thus, we can understand that the LCM of 209,980,240,324 is 66361680.
