Given numbers are 965,740,600,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 965,740,600,978 is 698389800.
Find LCM of 965,740,600,978 with Prime Factorization
| 2 | 965, 740, 600, 978 |
| 2 | 965, 370, 300, 489 |
| 3 | 965, 185, 150, 489 |
| 5 | 965, 185, 50, 163 |
| 193, 37, 10, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 193 x 37 x 10 x 163 = 698389800
Therefore, the lowest common multiple of 965,740,600,978 is 698389800.
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.
965 x 740 x 600 x 978 = 419033880000
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.
965 : 1, 5, 193, 965
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 965,740,600,978, is 1.
Now, the common factors can be found like this.
965:5x 193
740:2x 2x 5x 37
600:2x 2x 2x 3x 5x 5
978:2x 3x 163
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 = 419033880000/(1x600)
LCM = 419033880000/600
LCM = 698389800
Thus, we can understand that the LCM of 965,740,600,978 is 698389800.
