Given numbers are 91,67,70,898

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

The LCM of 91,67,70,898 is 27375530.

Find LCM of 91,67,70,898 with Prime Factorization

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

2 x 7 x 13 x 67 x 5 x 449 = 27375530

Therefore, the lowest common multiple of 91,67,70,898 is 27375530.

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.

91 x 67 x 70 x 898 = 383257420

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.

91 : 1, 7, 13, 91

67 : 1, 67

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

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 91,67,70,898, is 1.

Now, the common factors can be found like this.

91:7x 13

67:67

70:2x 5x 7

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 7 = 14

Therefore, the value for common factors is 14.

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 = 383257420/(1x14)

LCM = 383257420/14

LCM = 27375530

Thus, we can understand that the LCM of 91,67,70,898 is 27375530.

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

• LCM of 52, 17, 46, 735
