Calculate the LCM of 120,842,507,203

Given numbers are 120,842,507,203

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

The LCM of 120,842,507,203 is 1733189640.

Find LCM of 120,842,507,203 with Prime Factorization


2 120, 842, 507, 203
3 60, 421, 507, 203
20, 421, 169, 203

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

2 x 3 x 20 x 421 x 169 x 203 = 1733189640

Therefore, the lowest common multiple of 120,842,507,203 is 1733189640.

LCM Formula to Find Lowest Common Multiple of 120,842,507,203

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.

120 x 842 x 507 x 203 = 10399137840

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.

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

842 : 1, 2, 421, 842

507 : 1, 3, 13, 39, 169, 507

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,842,507,203, is 1.

Now, the common factors can be found like this.

120:2x 2x 2x 3x 5

842:2x 421

507:3x 13x 13

203:7x 29

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 10399137840/(1x6)

LCM = 10399137840/6

LCM = 1733189640

Thus, we can understand that the LCM of 120,842,507,203 is 1733189640.
