Given numbers are 210,174,578,742,193
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 210,174,578,742,193 is 18003142290.
Find LCM of 210,174,578,742,193 with Prime Factorization
| 2 | 210, 174, 578, 742, 193 |
| 3 | 105, 87, 289, 371, 193 |
| 7 | 35, 29, 289, 371, 193 |
| 5, 29, 289, 53, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 5 x 29 x 289 x 53 x 193 = 18003142290
Therefore, the lowest common multiple of 210,174,578,742,193 is 18003142290.
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.
210 x 174 x 578 x 742 x 193 = 3024527904720
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
174 : 1, 2, 3, 6, 29, 58, 87, 174
578 : 1, 2, 17, 34, 289, 578
742 : 1, 2, 7, 14, 53, 106, 371, 742
193 : 1, 193
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,174,578,742,193, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
174:2x 3x 29
578:2x 17x 17
742:2x 7x 53
193:193
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 3024527904720/(1x168)
LCM = 3024527904720/168
LCM = 18003142290
Thus, we can understand that the LCM of 210,174,578,742,193 is 18003142290.
