LCM Formula to Find Lowest Common Multiple of 128,138,209,980

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.

128 x 138 x 209 x 980 = 3617940480

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.

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

209 : 1, 11, 19, 209

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,138,209,980, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

138:2x 3x 23

209:11x 19

980:2x 2x 5x 7x 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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 3617940480/(1x8)

LCM = 3617940480/8

LCM = 452242560

Thus, we can understand that the LCM of 128,138,209,980 is 452242560.
