Given numbers are 121,385,860,505

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

The LCM of 121,385,860,505 is 73570420.

Find LCM of 121,385,860,505 with Prime Factorization

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

5 x 11 x 11 x 7 x 172 x 101 = 73570420

Therefore, the lowest common multiple of 121,385,860,505 is 73570420.

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 385 x 860 x 505 = 20231865500

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

385 : 1, 5, 7, 11, 35, 55, 77, 385

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,385,860,505, is 1.

Now, the common factors can be found like this.

121:11x 11

385:5x 7x 11

860:2x 2x 5x 43

505:5x 101

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

5x 5x 11 = 275

Therefore, the value for common factors is 275.

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 = 20231865500/(1x275)

LCM = 20231865500/275

LCM = 73570420

Thus, we can understand that the LCM of 121,385,860,505 is 73570420.

Here are some samples of LCM of two or more Numbers calculations.
