Find LCM of 132,840,989,784,175 with Prime Factorization
| 2 | 132, 840, 989, 784, 175 |
| 2 | 66, 420, 989, 392, 175 |
| 2 | 33, 210, 989, 196, 175 |
| 3 | 33, 105, 989, 98, 175 |
| 5 | 11, 35, 989, 98, 175 |
| 7 | 11, 7, 989, 98, 35 |
| 11, 1, 989, 14, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 11 x 1 x 989 x 14 x 5 = 639685200
Therefore, the lowest common multiple of 132,840,989,784,175 is 639685200.
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.
132 x 840 x 989 x 784 x 175 = 15045395904000
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.
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
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
989 : 1, 23, 43, 989
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 132,840,989,784,175, is 1.
Now, the common factors can be found like this.
132:2x 2x 3x 11
840:2x 2x 2x 3x 5x 7
989:23x 43
784:2x 2x 2x 2x 7x 7
175:5x 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 2x 2x 2x 3x 5x 7x 7 = 23520
Therefore, the value for common factors is 23520.
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 = 15045395904000/(1x23520)
LCM = 15045395904000/23520
LCM = 639685200
Thus, we can understand that the LCM of 132,840,989,784,175 is 639685200.
