Given numbers are 407,646,133,769

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

The LCM of 407,646,133,769 is 1415309126.

Find LCM of 407,646,133,769 with Prime Factorization

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

19 x 407 x 34 x 7 x 769 = 1415309126

Therefore, the lowest common multiple of 407,646,133,769 is 1415309126.

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 646 x 133 x 769 = 26890873394

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

133 : 1, 7, 19, 133

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,646,133,769, is 1.

Now, the common factors can be found like this.

407:11x 37

646:2x 17x 19

133:7x 19

769:769

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

19 = 19

Therefore, the value for common factors is 19.

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 = 26890873394/(1x19)

LCM = 26890873394/19

LCM = 1415309126

Thus, we can understand that the LCM of 407,646,133,769 is 1415309126.
