Find LCM of 822,847,280,984,780 with Prime Factorization
2 | 822, 847, 280, 984, 780 |
2 | 411, 847, 140, 492, 390 |
2 | 411, 847, 70, 246, 195 |
3 | 411, 847, 35, 123, 195 |
5 | 137, 847, 35, 41, 65 |
7 | 137, 847, 7, 41, 13 |
137, 121, 1, 41, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 137 x 121 x 1 x 41 x 13 = 7421854440
Therefore, the lowest common multiple of 822,847,280,984,780 is 7421854440.
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.
822 x 847 x 280 x 984 x 780 = 149624585510400
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
847 : 1, 7, 11, 77, 121, 847
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,847,280,984,780, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
847:7x 11x 11
280:2x 2x 2x 5x 7
984:2x 2x 2x 3x 41
780:2x 2x 3x 5x 13
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 2x 3x 3x 5x 7 = 20160
Therefore, the value for common factors is 20160.
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 = 149624585510400/(1x20160)
LCM = 149624585510400/20160
LCM = 7421854440
Thus, we can understand that the LCM of 822,847,280,984,780 is 7421854440.
