Given numbers are 132,220,210,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 132,220,210,770 is 4620.
Find LCM of 132,220,210,770 with Prime Factorization
| 2 | 132, 220, 210, 770 |
| 2 | 66, 110, 105, 385 |
| 3 | 33, 55, 105, 385 |
| 5 | 11, 55, 35, 385 |
| 7 | 11, 11, 7, 77 |
| 11 | 11, 11, 1, 11 |
| 1, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 1 x 1 x 1 x 1 = 4620
Therefore, the lowest common multiple of 132,220,210,770 is 4620.
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 220 x 210 x 770 = 4695768000
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
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 132,220,210,770, is 2.
Now, the common factors can be found like this.
132:2x 2x 3x 11
220:2x 2x 5x 11
210:2x 3x 5x 7
770:2x 5x 7x 11
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 3x 5x 5x 7x 11x 11 = 508200
Therefore, the value for common factors is 508200.
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 = 4695768000/(2x508200)
LCM = 4695768000/1016400
LCM = 4620
Thus, we can understand that the LCM of 132,220,210,770 is 4620.
