Find LCM of 947,126,141,840,890 with Prime Factorization
2 | 947, 126, 141, 840, 890 |
3 | 947, 63, 141, 420, 445 |
5 | 947, 21, 47, 140, 445 |
7 | 947, 21, 47, 28, 89 |
947, 3, 47, 4, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 947 x 3 x 47 x 4 x 89 = 9982478520
Therefore, the lowest common multiple of 947,126,141,840,890 is 9982478520.
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.
947 x 126 x 141 x 840 x 890 = 12577922935200
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.
947 : 1, 947
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
141 : 1, 3, 47, 141
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
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,126,141,840,890, is 1.
Now, the common factors can be found like this.
947:947
126:2x 3x 3x 7
141:3x 47
840:2x 2x 2x 3x 5x 7
890:2x 5x 89
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 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 12577922935200/(1x1260)
LCM = 12577922935200/1260
LCM = 9982478520
Thus, we can understand that the LCM of 947,126,141,840,890 is 9982478520.
