Given numbers are 978,822,851,652,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,822,851,652,745 is 169892908140.
Find LCM of 978,822,851,652,745 with Prime Factorization
| 2 | 978, 822, 851, 652, 745 |
| 3 | 489, 411, 851, 326, 745 |
| 163 | 163, 137, 851, 326, 745 |
| 1, 137, 851, 2, 745 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 1 x 137 x 851 x 2 x 745 = 169892908140
Therefore, the lowest common multiple of 978,822,851,652,745 is 169892908140.
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 822 x 851 x 652 x 745 = 332310528321840
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
822 : 1, 2, 3, 6, 137, 274, 411, 822
851 : 1, 23, 37, 851
652 : 1, 2, 4, 163, 326, 652
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,822,851,652,745, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
822:2x 3x 137
851:23x 37
652:2x 2x 163
745:5x 149
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 163 = 1956
Therefore, the value for common factors is 1956.
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 = 332310528321840/(1x1956)
LCM = 332310528321840/1956
LCM = 169892908140
Thus, we can understand that the LCM of 978,822,851,652,745 is 169892908140.
