Given numbers are 357,742,689,14
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,742,689,14 is 491946.
Find LCM of 357,742,689,14 with Prime Factorization
2 | 357, 742, 689, 14 |
7 | 357, 371, 689, 7 |
53 | 51, 53, 689, 1 |
51, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 53 x 51 x 1 x 13 x 1 = 491946
Therefore, the lowest common multiple of 357,742,689,14 is 491946.
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.
357 x 742 x 689 x 14 = 2555167524
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
742 : 1, 2, 7, 14, 53, 106, 371, 742
689 : 1, 13, 53, 689
14 : 1, 2, 7, 14
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,742,689,14, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
742:2x 7x 53
689:13x 53
14:2x 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 7x 7x 53 = 5194
Therefore, the value for common factors is 5194.
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 = 2555167524/(1x5194)
LCM = 2555167524/5194
LCM = 491946
Thus, we can understand that the LCM of 357,742,689,14 is 491946.
