Given numbers are 702,310,442,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 702,310,442,312 is 7399080.
Find LCM of 702,310,442,312 with Prime Factorization
| 2 | 702, 310, 442, 312 |
| 3 | 351, 155, 221, 156 |
| 13 | 117, 155, 221, 52 |
| 9, 155, 17, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 9 x 155 x 17 x 4 = 7399080
Therefore, the lowest common multiple of 702,310,442,312 is 7399080.
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.
702 x 310 x 442 x 312 = 30010668480
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.
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
310 : 1, 2, 5, 10, 31, 62, 155, 310
442 : 1, 2, 13, 17, 26, 34, 221, 442
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,310,442,312, is 2.
Now, the common factors can be found like this.
702:2x 3x 3x 3x 13
310:2x 5x 31
442:2x 13x 17
312:2x 2x 2x 3x 13
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 13x 13 = 2028
Therefore, the value for common factors is 2028.
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 = 30010668480/(2x2028)
LCM = 30010668480/4056
LCM = 7399080
Thus, we can understand that the LCM of 702,310,442,312 is 7399080.
