Given numbers are 74,70,31,898

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

The LCM of 74,70,31,898 is 36050210.

Find LCM of 74,70,31,898 with Prime Factorization

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

2 x 37 x 35 x 31 x 449 = 36050210

Therefore, the lowest common multiple of 74,70,31,898 is 36050210.

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.

74 x 70 x 31 x 898 = 144200840

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.

74 : 1, 2, 37, 74

70 : 1, 2, 5, 7, 10, 14, 35, 70

31 : 1, 31

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 74,70,31,898, is 1.

Now, the common factors can be found like this.

74:2x 37

70:2x 5x 7

31:31

898:2x 449

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 144200840/(1x4)

LCM = 144200840/4

LCM = 36050210

Thus, we can understand that the LCM of 74,70,31,898 is 36050210.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 14, 42, 80, 700
