Given numbers are 978,707,404,136
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,707,404,136 is 47018328.
Find LCM of 978,707,404,136 with Prime Factorization
| 2 | 978, 707, 404, 136 |
| 2 | 489, 707, 202, 68 |
| 101 | 489, 707, 101, 34 |
| 489, 7, 1, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 489 x 7 x 1 x 34 = 47018328
Therefore, the lowest common multiple of 978,707,404,136 is 47018328.
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.
978 x 707 x 404 x 136 = 37990809024
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
707 : 1, 7, 101, 707
404 : 1, 2, 4, 101, 202, 404
136 : 1, 2, 4, 8, 17, 34, 68, 136
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,707,404,136, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
707:7x 101
404:2x 2x 101
136:2x 2x 2x 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 2x 2x 101 = 808
Therefore, the value for common factors is 808.
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 = 37990809024/(1x808)
LCM = 37990809024/808
LCM = 47018328
Thus, we can understand that the LCM of 978,707,404,136 is 47018328.
