Given numbers are 45,31,31,46,121

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

The LCM of 45,31,31,46,121 is 7764570.

Find LCM of 45,31,31,46,121 with Prime Factorization

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

31 x 45 x 1 x 1 x 46 x 121 = 7764570

Therefore, the lowest common multiple of 45,31,31,46,121 is 7764570.

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.

45 x 31 x 31 x 46 x 121 = 240701670

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.

45 : 1, 3, 5, 9, 15, 45

31 : 1, 31

31 : 1, 31

46 : 1, 2, 23, 46

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 45,31,31,46,121, is 1.

Now, the common factors can be found like this.

45:3x 3x 5

31:31

31:31

46:2x 23

121:11x 11

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

31 = 31

Therefore, the value for common factors is 31.

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 = 240701670/(1x31)

LCM = 240701670/31

LCM = 7764570

Thus, we can understand that the LCM of 45,31,31,46,121 is 7764570.
