Find LCM of 892,305,840,680,138 with Prime Factorization
2 | 892, 305, 840, 680, 138 |
2 | 446, 305, 420, 340, 69 |
2 | 223, 305, 210, 170, 69 |
3 | 223, 305, 105, 85, 69 |
5 | 223, 305, 35, 85, 23 |
223, 61, 7, 17, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 223 x 61 x 7 x 17 x 23 = 4467769320
Therefore, the lowest common multiple of 892,305,840,680,138 is 4467769320.
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.
892 x 305 x 840 x 680 x 138 = 21445292736000
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.
892 : 1, 2, 4, 223, 446, 892
305 : 1, 5, 61, 305
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,305,840,680,138, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
305:5x 61
840:2x 2x 2x 3x 5x 7
680:2x 2x 2x 5x 17
138:2x 3x 23
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 5x 5 = 4800
Therefore, the value for common factors is 4800.
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 = 21445292736000/(1x4800)
LCM = 21445292736000/4800
LCM = 4467769320
Thus, we can understand that the LCM of 892,305,840,680,138 is 4467769320.
