Find LCM of 746,147,342,839,840 with Prime Factorization
2 | 746, 147, 342, 839, 840 |
3 | 373, 147, 171, 839, 420 |
7 | 373, 49, 57, 839, 140 |
373, 7, 57, 839, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 373 x 7 x 57 x 839 x 20 = 104887316520
Therefore, the lowest common multiple of 746,147,342,839,840 is 104887316520.
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.
746 x 147 x 342 x 839 x 840 = 26431603763040
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.
746 : 1, 2, 373, 746
147 : 1, 3, 7, 21, 49, 147
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
839 : 1, 839
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,147,342,839,840, is 1.
Now, the common factors can be found like this.
746:2x 373
147:3x 7x 7
342:2x 3x 3x 19
839:839
840:2x 2x 2x 3x 5x 7
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 26431603763040/(1x252)
LCM = 26431603763040/252
LCM = 104887316520
Thus, we can understand that the LCM of 746,147,342,839,840 is 104887316520.
