Calculate the LCM of 447,615,533,421

Given numbers are 447,615,533,421

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

The LCM of 447,615,533,421 is 501518355.

Find LCM of 447,615,533,421 with Prime Factorization


3 447, 615, 533, 421
41 149, 205, 533, 421
149, 5, 13, 421

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

3 x 41 x 149 x 5 x 13 x 421 = 501518355

Therefore, the lowest common multiple of 447,615,533,421 is 501518355.

LCM Formula to Find Lowest Common Multiple of 447,615,533,421

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.

447 x 615 x 533 x 421 = 61686757665

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.

447 : 1, 3, 149, 447

615 : 1, 3, 5, 15, 41, 123, 205, 615

533 : 1, 13, 41, 533

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,615,533,421, is 1.

Now, the common factors can be found like this.

447:3x 149

615:3x 5x 41

533:13x 41

421:421

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

3x 41 = 123

Therefore, the value for common factors is 123.

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 = 61686757665/(1x123)

LCM = 61686757665/123

LCM = 501518355

Thus, we can understand that the LCM of 447,615,533,421 is 501518355.
