Calculate the LCM of 655,655,203,442

Given numbers are 655,655,203,442

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

The LCM of 655,655,203,442 is 58770530.

Find LCM of 655,655,203,442 with Prime Factorization


5 655, 655, 203, 442
131 131, 131, 203, 442
1, 1, 203, 442

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

5 x 131 x 1 x 1 x 203 x 442 = 58770530

Therefore, the lowest common multiple of 655,655,203,442 is 58770530.

LCM Formula to Find Lowest Common Multiple of 655,655,203,442

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.

655 x 655 x 203 x 442 = 38494697150

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.

655 : 1, 5, 131, 655

655 : 1, 5, 131, 655

203 : 1, 7, 29, 203

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,655,203,442, is 1.

Now, the common factors can be found like this.

655:5x 131

655:5x 131

203:7x 29

442:2x 13x 17

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

5x 131 = 655

Therefore, the value for common factors is 655.

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 = 38494697150/(1x655)

LCM = 38494697150/655

LCM = 58770530

Thus, we can understand that the LCM of 655,655,203,442 is 58770530.
