Given numbers are 140,399,361,605,322
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,399,361,605,322 is 421958460.
Find LCM of 140,399,361,605,322 with Prime Factorization
| 2 | 140, 399, 361, 605, 322 |
| 5 | 70, 399, 361, 605, 161 |
| 7 | 14, 399, 361, 121, 161 |
| 19 | 2, 57, 361, 121, 23 |
| 2, 3, 19, 121, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 19 x 2 x 3 x 19 x 121 x 23 = 421958460
Therefore, the lowest common multiple of 140,399,361,605,322 is 421958460.
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.
140 x 399 x 361 x 605 x 322 = 3928433262600
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
399 : 1, 3, 7, 19, 21, 57, 133, 399
361 : 1, 19, 361
605 : 1, 5, 11, 55, 121, 605
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,399,361,605,322, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
399:3x 7x 19
361:19x 19
605:5x 11x 11
322:2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7x 19 = 9310
Therefore, the value for common factors is 9310.
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 = 3928433262600/(1x9310)
LCM = 3928433262600/9310
LCM = 421958460
Thus, we can understand that the LCM of 140,399,361,605,322 is 421958460.
