Find LCM of 153,189,210,635,980 with Prime Factorization
| 2 | 153, 189, 210, 635, 980 |
| 3 | 153, 189, 105, 635, 490 |
| 3 | 51, 63, 35, 635, 490 |
| 5 | 17, 21, 35, 635, 490 |
| 7 | 17, 21, 7, 127, 98 |
| 17, 3, 1, 127, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 17 x 3 x 1 x 127 x 14 = 57127140
Therefore, the lowest common multiple of 153,189,210,635,980 is 57127140.
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.
153 x 189 x 210 x 635 x 980 = 3778960311000
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.
153 : 1, 3, 9, 17, 51, 153
189 : 1, 3, 7, 9, 21, 27, 63, 189
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
635 : 1, 5, 127, 635
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,189,210,635,980, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
189:3x 3x 3x 7
210:2x 3x 5x 7
635:5x 127
980:2x 2x 5x 7x 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 3x 3x 3x 5x 5x 7x 7 = 66150
Therefore, the value for common factors is 66150.
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 = 3778960311000/(1x66150)
LCM = 3778960311000/66150
LCM = 57127140
Thus, we can understand that the LCM of 153,189,210,635,980 is 57127140.
