Calculate the LCM of 961,403,361,242

Given numbers are 961,403,361,242

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

The LCM of 961,403,361,242 is 1091413466.

Find LCM of 961,403,361,242 with Prime Factorization


31 961, 403, 361, 242
31, 13, 361, 242

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

31 x 31 x 13 x 361 x 242 = 1091413466

Therefore, the lowest common multiple of 961,403,361,242 is 1091413466.

LCM Formula to Find Lowest Common Multiple of 961,403,361,242

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.

961 x 403 x 361 x 242 = 33833817446

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.

961 : 1, 31, 961

403 : 1, 13, 31, 403

361 : 1, 19, 361

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,403,361,242, is 1.

Now, the common factors can be found like this.

961:31x 31

403:13x 31

361:19x 19

242:2x 11x 11

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 = 33833817446/(1x31)

LCM = 33833817446/31

LCM = 1091413466

Thus, we can understand that the LCM of 961,403,361,242 is 1091413466.
