Given numbers are 623,702,742,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,702,742,611 is 1089428886.
Find LCM of 623,702,742,611 with Prime Factorization
| 2 | 623, 702, 742, 611 |
| 7 | 623, 351, 371, 611 |
| 13 | 89, 351, 53, 611 |
| 89, 27, 53, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 89 x 27 x 53 x 47 = 1089428886
Therefore, the lowest common multiple of 623,702,742,611 is 1089428886.
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.
623 x 702 x 742 x 611 = 198276057252
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.
623 : 1, 7, 89, 623
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
742 : 1, 2, 7, 14, 53, 106, 371, 742
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,702,742,611, is 1.
Now, the common factors can be found like this.
623:7x 89
702:2x 3x 3x 3x 13
742:2x 7x 53
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 198276057252/(1x182)
LCM = 198276057252/182
LCM = 1089428886
Thus, we can understand that the LCM of 623,702,742,611 is 1089428886.
