Given numbers are 418,865,570,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,865,570,310 is 33626010.
Find LCM of 418,865,570,310 with Prime Factorization
| 2 | 418, 865, 570, 310 |
| 5 | 209, 865, 285, 155 |
| 19 | 209, 173, 57, 31 |
| 11, 173, 3, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 11 x 173 x 3 x 31 = 33626010
Therefore, the lowest common multiple of 418,865,570,310 is 33626010.
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.
418 x 865 x 570 x 310 = 63889419000
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
865 : 1, 5, 173, 865
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,865,570,310, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
865:5x 173
570:2x 3x 5x 19
310:2x 5x 31
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 5x 5x 19 = 1900
Therefore, the value for common factors is 1900.
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 = 63889419000/(1x1900)
LCM = 63889419000/1900
LCM = 33626010
Thus, we can understand that the LCM of 418,865,570,310 is 33626010.
