Given numbers are 921,978,835,870,952
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,978,835,870,952 is 3460737479640.
Find LCM of 921,978,835,870,952 with Prime Factorization
| 2 | 921, 978, 835, 870, 952 |
| 3 | 921, 489, 835, 435, 476 |
| 5 | 307, 163, 835, 145, 476 |
| 307, 163, 167, 29, 476 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 307 x 163 x 167 x 29 x 476 = 3460737479640
Therefore, the lowest common multiple of 921,978,835,870,952 is 3460737479640.
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.
921 x 978 x 835 x 870 x 952 = 622932746335200
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.
921 : 1, 3, 307, 921
978 : 1, 2, 3, 6, 163, 326, 489, 978
835 : 1, 5, 167, 835
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,978,835,870,952, is 1.
Now, the common factors can be found like this.
921:3x 307
978:2x 3x 163
835:5x 167
870:2x 3x 5x 29
952:2x 2x 2x 7x 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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 622932746335200/(1x180)
LCM = 622932746335200/180
LCM = 3460737479640
Thus, we can understand that the LCM of 921,978,835,870,952 is 3460737479640.
