Given numbers are 407,637,133,969

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

The LCM of 407,637,133,969 is 251221971.

Find LCM of 407,637,133,969 with Prime Factorization

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

7 x 19 x 407 x 91 x 1 x 51 = 251221971

Therefore, the lowest common multiple of 407,637,133,969 is 251221971.

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.

407 x 637 x 133 x 969 = 33412522143

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.

407 : 1, 11, 37, 407

637 : 1, 7, 13, 49, 91, 637

133 : 1, 7, 19, 133

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,637,133,969, is 1.

Now, the common factors can be found like this.

407:11x 37

637:7x 7x 13

133:7x 19

969:3x 17x 19

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

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 33412522143/(1x133)

LCM = 33412522143/133

LCM = 251221971

Thus, we can understand that the LCM of 407,637,133,969 is 251221971.
