Given numbers are 906,661,689,424

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

The LCM of 906,661,689,424 is 1650474696.

Find LCM of 906,661,689,424 with Prime Factorization

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

2 x 53 x 453 x 661 x 13 x 4 = 1650474696

Therefore, the lowest common multiple of 906,661,689,424 is 1650474696.

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 661 x 689 x 424 = 174950317776

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

661 : 1, 661

689 : 1, 13, 53, 689

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,661,689,424, is 1.

Now, the common factors can be found like this.

906:2x 3x 151

661:661

689:13x 53

424:2x 2x 2x 53

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 174950317776/(1x106)

LCM = 174950317776/106

LCM = 1650474696

Thus, we can understand that the LCM of 906,661,689,424 is 1650474696.
