Given numbers are 318,835,420,155,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 318,835,420,155,478 is 27542364780.
Find LCM of 318,835,420,155,478 with Prime Factorization
| 2 | 318, 835, 420, 155, 478 |
| 3 | 159, 835, 210, 155, 239 |
| 5 | 53, 835, 70, 155, 239 |
| 53, 167, 14, 31, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 53 x 167 x 14 x 31 x 239 = 27542364780
Therefore, the lowest common multiple of 318,835,420,155,478 is 27542364780.
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.
318 x 835 x 420 x 155 x 478 = 8262709434000
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
835 : 1, 5, 167, 835
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
155 : 1, 5, 31, 155
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,835,420,155,478, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
835:5x 167
420:2x 2x 3x 5x 7
155:5x 31
478:2x 239
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 8262709434000/(1x300)
LCM = 8262709434000/300
LCM = 27542364780
Thus, we can understand that the LCM of 318,835,420,155,478 is 27542364780.
