Calculate the LCM of 661,655,655,103

Given numbers are 661,655,655,103

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

The LCM of 661,655,655,103 is 44594365.

Find LCM of 661,655,655,103 with Prime Factorization


5 661, 655, 655, 103
131 661, 131, 131, 103
661, 1, 1, 103

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

5 x 131 x 661 x 1 x 1 x 103 = 44594365

Therefore, the lowest common multiple of 661,655,655,103 is 44594365.

LCM Formula to Find Lowest Common Multiple of 661,655,655,103

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.

661 x 655 x 655 x 103 = 29209309075

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.

661 : 1, 661

655 : 1, 5, 131, 655

655 : 1, 5, 131, 655

103 : 1, 103

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,655,655,103, is 1.

Now, the common factors can be found like this.

661:661

655:5x 131

655:5x 131

103:103

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 = 29209309075/(1x655)

LCM = 29209309075/655

LCM = 44594365

Thus, we can understand that the LCM of 661,655,655,103 is 44594365.
