Given numbers are 648,906,735,806,391

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 648,906,735,806,391 is 3777459711480.

Find LCM of 648,906,735,806,391 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 108 x 151 x 245 x 403 x 391 = 3777459711480

Therefore, the lowest common multiple of 648,906,735,806,391 is 3777459711480.

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.

648 x 906 x 735 x 806 x 391 = 135988549613280

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

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

735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735

806 : 1, 2, 13, 26, 31, 62, 403, 806

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,906,735,806,391, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

906:2x 3x 151

735:3x 5x 7x 7

806:2x 13x 31

391:17x 23

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 3 = 36

Therefore, the value for common factors is 36.

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 = 135988549613280/(1x36)

LCM = 135988549613280/36

LCM = 3777459711480

Thus, we can understand that the LCM of 648,906,735,806,391 is 3777459711480.
