Given numbers are 72,85,41,19,418

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

The LCM of 72,85,41,19,418 is 52442280.

Find LCM of 72,85,41,19,418 with Prime Factorization

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

2 x 19 x 36 x 85 x 41 x 1 x 11 = 52442280

Therefore, the lowest common multiple of 72,85,41,19,418 is 52442280.

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.

72 x 85 x 41 x 19 x 418 = 1992806640

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.

72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

85 : 1, 5, 17, 85

41 : 1, 41

19 : 1, 19

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 72,85,41,19,418, is 1.

Now, the common factors can be found like this.

72:2x 2x 2x 3x 3

85:5x 17

41:41

19:19

418:2x 11x 19

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 1992806640/(1x38)

LCM = 1992806640/38

LCM = 52442280

Thus, we can understand that the LCM of 72,85,41,19,418 is 52442280.
