Given numbers are 31,29,31,68,551

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

The LCM of 31,29,31,68,551 is 1161508.

Find LCM of 31,29,31,68,551 with Prime Factorization

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

29 x 31 x 1 x 1 x 1 x 68 x 19 = 1161508

Therefore, the lowest common multiple of 31,29,31,68,551 is 1161508.

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.

31 x 29 x 31 x 68 x 551 = 1044195692

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.

31 : 1, 31

29 : 1, 29

31 : 1, 31

68 : 1, 2, 4, 17, 34, 68

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 31,29,31,68,551, is 1.

Now, the common factors can be found like this.

31:31

29:29

31:31

68:2x 2x 17

551:19x 29

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

29x 31 = 899

Therefore, the value for common factors is 899.

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 = 1044195692/(1x899)

LCM = 1044195692/899

LCM = 1161508

Thus, we can understand that the LCM of 31,29,31,68,551 is 1161508.
