Given numbers are 169,91,109

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

The LCM of 169,91,109 is 128947.

Find LCM of 169,91,109 with Prime Factorization

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

13 x 13 x 7 x 109 = 128947

Therefore, the lowest common multiple of 169,91,109 is 128947.

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.

169 x 91 x 109 = 1676311

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.

169 : 1, 13, 169

91 : 1, 7, 13, 91

109 : 1, 109

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,91,109, is 1.

Now, the common factors can be found like this.

169:13x 13

91:7x 13

109:109

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

13 = 13

Therefore, the value for common factors is 13.

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 = 1676311/(1x13)

LCM = 1676311/13

LCM = 128947

Thus, we can understand that the LCM of 169,91,109 is 128947.

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

• LCM of 974, 65, 735
• LCM of 811, 59, 889
