LCM Formula to Find Lowest Common Multiple of 690,256,704,967,657

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.

690 x 256 x 704 x 967 x 657 = 79004814704640

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

967 : 1, 967

657 : 1, 3, 9, 73, 219, 657

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,256,704,967,657, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

256:2x 2x 2x 2x 2x 2x 2x 2

704:2x 2x 2x 2x 2x 2x 11

967:967

657:3x 3x 73

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 3 = 384

Therefore, the value for common factors is 384.

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 = 79004814704640/(1x384)

LCM = 79004814704640/384

LCM = 205741704960

Thus, we can understand that the LCM of 690,256,704,967,657 is 205741704960.
