Given numbers are 756,723,163,117
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,723,163,117 is 386073324.
Find LCM of 756,723,163,117 with Prime Factorization
3 | 756, 723, 163, 117 |
3 | 252, 241, 163, 39 |
84, 241, 163, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 84 x 241 x 163 x 13 = 386073324
Therefore, the lowest common multiple of 756,723,163,117 is 386073324.
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.
756 x 723 x 163 x 117 = 10423979748
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
723 : 1, 3, 241, 723
163 : 1, 163
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,723,163,117, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
723:3x 241
163:163
117:3x 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.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 10423979748/(1x27)
LCM = 10423979748/27
LCM = 386073324
Thus, we can understand that the LCM of 756,723,163,117 is 386073324.
