Given numbers are 389,303,210,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,303,210,374 is 1542879030.
Find LCM of 389,303,210,374 with Prime Factorization
| 2 | 389, 303, 210, 374 |
| 3 | 389, 303, 105, 187 |
| 389, 101, 35, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 389 x 101 x 35 x 187 = 1542879030
Therefore, the lowest common multiple of 389,303,210,374 is 1542879030.
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.
389 x 303 x 210 x 374 = 9257274180
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.
389 : 1, 389
303 : 1, 3, 101, 303
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,303,210,374, is 1.
Now, the common factors can be found like this.
389:389
303:3x 101
210:2x 3x 5x 7
374:2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 9257274180/(1x6)
LCM = 9257274180/6
LCM = 1542879030
Thus, we can understand that the LCM of 389,303,210,374 is 1542879030.
