Given numbers are 169,780,179,170,154

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

The LCM of 169,780,179,170,154 is 2375913540.

Find LCM of 169,780,179,170,154 with Prime Factorization

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

2 x 5 x 13 x 13 x 6 x 179 x 17 x 77 = 2375913540

Therefore, the lowest common multiple of 169,780,179,170,154 is 2375913540.

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 780 x 179 x 170 x 154 = 617737520400

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

179 : 1, 179

170 : 1, 2, 5, 10, 17, 34, 85, 170

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,780,179,170,154, is 1.

Now, the common factors can be found like this.

169:13x 13

780:2x 2x 3x 5x 13

179:179

170:2x 5x 17

154:2x 7x 11

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

2x 2x 5x 13 = 260

Therefore, the value for common factors is 260.

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 = 617737520400/(1x260)

LCM = 617737520400/260

LCM = 2375913540

Thus, we can understand that the LCM of 169,780,179,170,154 is 2375913540.
