Given numbers are 645,575,161,853

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

The LCM of 645,575,161,853 is 442898925.

Find LCM of 645,575,161,853 with Prime Factorization

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

5 x 23 x 129 x 5 x 7 x 853 = 442898925

Therefore, the lowest common multiple of 645,575,161,853 is 442898925.

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.

645 x 575 x 161 x 853 = 50933376375

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

575 : 1, 5, 23, 25, 115, 575

161 : 1, 7, 23, 161

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,575,161,853, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

575:5x 5x 23

161:7x 23

853:853

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

5x 23 = 115

Therefore, the value for common factors is 115.

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 = 50933376375/(1x115)

LCM = 50933376375/115

LCM = 442898925

Thus, we can understand that the LCM of 645,575,161,853 is 442898925.
