Given numbers are 169,371,392,245

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

The LCM of 169,371,392,245 is 17555720.

Find LCM of 169,371,392,245 with Prime Factorization

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

7 x 7 x 169 x 53 x 8 x 5 = 17555720

Therefore, the lowest common multiple of 169,371,392,245 is 17555720.

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 371 x 392 x 245 = 6021611960

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

371 : 1, 7, 53, 371

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

245 : 1, 5, 7, 35, 49, 245

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,371,392,245, is 1.

Now, the common factors can be found like this.

169:13x 13

371:7x 53

392:2x 2x 2x 7x 7

245:5x 7x 7

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

7x 7x 7 = 343

Therefore, the value for common factors is 343.

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 = 6021611960/(1x343)

LCM = 6021611960/343

LCM = 17555720

Thus, we can understand that the LCM of 169,371,392,245 is 17555720.
