Given numbers are 210,978,745,466,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 210,978,745,466,423 is 167559170310.
Find LCM of 210,978,745,466,423 with Prime Factorization
| 2 | 210, 978, 745, 466, 423 |
| 3 | 105, 489, 745, 233, 423 |
| 5 | 35, 163, 745, 233, 141 |
| 7, 163, 149, 233, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 163 x 149 x 233 x 141 = 167559170310
Therefore, the lowest common multiple of 210,978,745,466,423 is 167559170310.
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 978 x 745 x 466 x 423 = 30160650655800
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
978 : 1, 2, 3, 6, 163, 326, 489, 978
745 : 1, 5, 149, 745
466 : 1, 2, 233, 466
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,978,745,466,423, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
978:2x 3x 163
745:5x 149
466:2x 233
423:3x 3x 47
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 30160650655800/(1x180)
LCM = 30160650655800/180
LCM = 167559170310
Thus, we can understand that the LCM of 210,978,745,466,423 is 167559170310.
