Given numbers are 618,561,748,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 618,561,748,746 is 86212236.
Find LCM of 618,561,748,746 with Prime Factorization
2 | 618, 561, 748, 746 |
3 | 309, 561, 374, 373 |
11 | 103, 187, 374, 373 |
17 | 103, 17, 34, 373 |
103, 1, 2, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 103 x 1 x 2 x 373 = 86212236
Therefore, the lowest common multiple of 618,561,748,746 is 86212236.
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.
618 x 561 x 748 x 746 = 193460257584
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
561 : 1, 3, 11, 17, 33, 51, 187, 561
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,561,748,746, is 1.
Now, the common factors can be found like this.
618:2x 3x 103
561:3x 11x 17
748:2x 2x 11x 17
746:2x 373
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 11x 17 = 2244
Therefore, the value for common factors is 2244.
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 = 193460257584/(1x2244)
LCM = 193460257584/2244
LCM = 86212236
Thus, we can understand that the LCM of 618,561,748,746 is 86212236.
