Find LCM of 984,390,508,428,765 with Prime Factorization
2 | 984, 390, 508, 428, 765 |
2 | 492, 195, 254, 214, 765 |
3 | 246, 195, 127, 107, 765 |
5 | 82, 65, 127, 107, 255 |
82, 13, 127, 107, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 82 x 13 x 127 x 107 x 51 = 44326774440
Therefore, the lowest common multiple of 984,390,508,428,765 is 44326774440.
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.
984 x 390 x 508 x 428 x 765 = 63830555193600
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
508 : 1, 2, 4, 127, 254, 508
428 : 1, 2, 4, 107, 214, 428
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,390,508,428,765, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
390:2x 3x 5x 13
508:2x 2x 127
428:2x 2x 107
765:3x 3x 5x 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 2x 2x 2x 3x 3x 5 = 1440
Therefore, the value for common factors is 1440.
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 = 63830555193600/(1x1440)
LCM = 63830555193600/1440
LCM = 44326774440
Thus, we can understand that the LCM of 984,390,508,428,765 is 44326774440.
