Calculate the LCM of 121,242,901,559

Given numbers are 121,242,901,559

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

The LCM of 121,242,901,559 is 121885478.

Find LCM of 121,242,901,559 with Prime Factorization


11 121, 242, 901, 559
11 11, 22, 901, 559
1, 2, 901, 559

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

11 x 11 x 1 x 2 x 901 x 559 = 121885478

Therefore, the lowest common multiple of 121,242,901,559 is 121885478.

LCM Formula to Find Lowest Common Multiple of 121,242,901,559

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.

121 x 242 x 901 x 559 = 14748142838

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.

121 : 1, 11, 121

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

901 : 1, 17, 53, 901

559 : 1, 13, 43, 559

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,242,901,559, is 1.

Now, the common factors can be found like this.

121:11x 11

242:2x 11x 11

901:17x 53

559:13x 43

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 14748142838/(1x121)

LCM = 14748142838/121

LCM = 121885478

Thus, we can understand that the LCM of 121,242,901,559 is 121885478.
