The LCM of 978,740,865,335,624 is 218104601520.
Find LCM of 978,740,865,335,624 with Prime Factorization
| 2 | 978, 740, 865, 335, 624 |
| 2 | 489, 370, 865, 335, 312 |
| 3 | 489, 185, 865, 335, 156 |
| 5 | 163, 185, 865, 335, 52 |
| 163, 37, 173, 67, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 163 x 37 x 173 x 67 x 52 = 218104601520
Therefore, the lowest common multiple of 978,740,865,335,624 is 218104601520.
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 740 x 865 x 335 x 624 = 130862760912000
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
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
865 : 1, 5, 173, 865
335 : 1, 5, 67, 335
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,740,865,335,624, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
740:2x 2x 5x 37
865:5x 173
335:5x 67
624:2x 2x 2x 2x 3x 13
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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 130862760912000/(1x600)
LCM = 130862760912000/600
LCM = 218104601520
Thus, we can understand that the LCM of 978,740,865,335,624 is 218104601520.
