Find LCM of 998,791,639,420,765 with Prime Factorization
2 | 998, 791, 639, 420, 765 |
3 | 499, 791, 639, 210, 765 |
3 | 499, 791, 213, 70, 255 |
5 | 499, 791, 71, 70, 85 |
7 | 499, 791, 71, 14, 17 |
499, 113, 71, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 499 x 113 x 71 x 2 x 17 = 85754477340
Therefore, the lowest common multiple of 998,791,639,420,765 is 85754477340.
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.
998 x 791 x 639 x 420 x 765 = 162075962172600
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.
998 : 1, 2, 499, 998
791 : 1, 7, 113, 791
639 : 1, 3, 9, 71, 213, 639
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
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 998,791,639,420,765, is 1.
Now, the common factors can be found like this.
998:2x 499
791:7x 113
639:3x 3x 71
420:2x 2x 3x 5x 7
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 3x 3x 3x 5x 7 = 1890
Therefore, the value for common factors is 1890.
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 = 162075962172600/(1x1890)
LCM = 162075962172600/1890
LCM = 85754477340
Thus, we can understand that the LCM of 998,791,639,420,765 is 85754477340.
