LCM Formula to Find Lowest Common Multiple of 906,385,828,838,639

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.

906 x 385 x 828 x 838 x 639 = 154655062475760

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.

906 : 1, 2, 3, 6, 151, 302, 453, 906

385 : 1, 5, 7, 11, 35, 55, 77, 385

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

838 : 1, 2, 419, 838

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,385,828,838,639, is 1.

Now, the common factors can be found like this.

906:2x 3x 151

385:5x 7x 11

828:2x 2x 3x 3x 23

838:2x 419

639:3x 3x 71

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 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 154655062475760/(1x108)

LCM = 154655062475760/108

LCM = 1431991319220

Thus, we can understand that the LCM of 906,385,828,838,639 is 1431991319220.
