Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 19 x 13 x 1 x 5 x 2 = 948480
Therefore, the lowest common multiple of 741,128,380,768 is 948480.
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.
741 x 128 x 380 x 768 = 27680440320
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
128 : 1, 2, 4, 8, 16, 32, 64, 128
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,128,380,768, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
128:2x 2x 2x 2x 2x 2x 2
380:2x 2x 5x 19
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 2x 2x 2x 2x 2x 2x 2x 3x 19 = 29184
Therefore, the value for common factors is 29184.
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 = 27680440320/(1x29184)
LCM = 27680440320/29184
LCM = 948480
Thus, we can understand that the LCM of 741,128,380,768 is 948480.
