Given numbers are 403,133,157,155

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

The LCM of 403,133,157,155 is 42075215.

Find LCM of 403,133,157,155 with Prime Factorization

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

31 x 13 x 133 x 157 x 5 = 42075215

Therefore, the lowest common multiple of 403,133,157,155 is 42075215.

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.

403 x 133 x 157 x 155 = 1304331665

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.

403 : 1, 13, 31, 403

133 : 1, 7, 19, 133

157 : 1, 157

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,133,157,155, is 1.

Now, the common factors can be found like this.

403:13x 31

133:7x 19

157:157

155:5x 31

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 = 1304331665/(1x31)

LCM = 1304331665/31

LCM = 42075215

Thus, we can understand that the LCM of 403,133,157,155 is 42075215.
