Given numbers are 220,702,708,885
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,702,708,885 is 4555980.
Find LCM of 220,702,708,885 with Prime Factorization
| 2 | 220, 702, 708, 885 |
| 2 | 110, 351, 354, 885 |
| 3 | 55, 351, 177, 885 |
| 5 | 55, 117, 59, 295 |
| 59 | 11, 117, 59, 59 |
| 11, 117, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 59 x 11 x 117 x 1 x 1 = 4555980
Therefore, the lowest common multiple of 220,702,708,885 is 4555980.
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.
220 x 702 x 708 x 885 = 96769015200
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,702,708,885, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
702:2x 3x 3x 3x 13
708:2x 2x 3x 59
885:3x 5x 59
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 3x 5x 59 = 21240
Therefore, the value for common factors is 21240.
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 = 96769015200/(1x21240)
LCM = 96769015200/21240
LCM = 4555980
Thus, we can understand that the LCM of 220,702,708,885 is 4555980.
