Calculate the LCM of 481,561,715,491

Given numbers are 481,561,715,491

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

The LCM of 481,561,715,491 is 662459655.

Find LCM of 481,561,715,491 with Prime Factorization


11 481, 561, 715, 491
13 481, 51, 65, 491
37, 51, 5, 491

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

11 x 13 x 37 x 51 x 5 x 491 = 662459655

Therefore, the lowest common multiple of 481,561,715,491 is 662459655.

LCM Formula to Find Lowest Common Multiple of 481,561,715,491

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.

481 x 561 x 715 x 491 = 94731730665

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.

481 : 1, 13, 37, 481

561 : 1, 3, 11, 17, 33, 51, 187, 561

715 : 1, 5, 11, 13, 55, 65, 143, 715

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,561,715,491, is 1.

Now, the common factors can be found like this.

481:13x 37

561:3x 11x 17

715:5x 11x 13

491:491

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 94731730665/(1x143)

LCM = 94731730665/143

LCM = 662459655

Thus, we can understand that the LCM of 481,561,715,491 is 662459655.
