Find LCM of 746,189,281,756 with Prime Factorization
2 | 746, 189, 281, 756 |
3 | 373, 189, 281, 378 |
3 | 373, 63, 281, 126 |
3 | 373, 21, 281, 42 |
7 | 373, 7, 281, 14 |
373, 1, 281, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 373 x 1 x 281 x 2 = 79238628
Therefore, the lowest common multiple of 746,189,281,756 is 79238628.
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.
746 x 189 x 281 x 756 = 29952201384
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.
746 : 1, 2, 373, 746
189 : 1, 3, 7, 9, 21, 27, 63, 189
281 : 1, 281
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,189,281,756, is 1.
Now, the common factors can be found like this.
746:2x 373
189:3x 3x 3x 7
281:281
756:2x 2x 3x 3x 3x 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 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 29952201384/(1x378)
LCM = 29952201384/378
LCM = 79238628
Thus, we can understand that the LCM of 746,189,281,756 is 79238628.
