Find LCM of 879,675,648,978 with Prime Factorization
2 | 879, 675, 648, 978 |
3 | 879, 675, 324, 489 |
3 | 293, 225, 108, 163 |
3 | 293, 75, 36, 163 |
293, 25, 12, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 293 x 25 x 12 x 163 = 773695800
Therefore, the lowest common multiple of 879,675,648,978 is 773695800.
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.
879 x 675 x 648 x 978 = 376016158800
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.
879 : 1, 3, 293, 879
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
978 : 1, 2, 3, 6, 163, 326, 489, 978
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 879,675,648,978, is 3.
Now, the common factors can be found like this.
879:3x 293
675:3x 3x 3x 5x 5
648:2x 2x 2x 3x 3x 3x 3
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 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 376016158800/(3x162)
LCM = 376016158800/486
LCM = 773695800
Thus, we can understand that the LCM of 879,675,648,978 is 773695800.
