Calculate the LCM of 215,391,465,122

Given numbers are 215,391,465,122

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

The LCM of 215,391,465,122 is 953801490.

Find LCM of 215,391,465,122 with Prime Factorization


5 215, 391, 465, 122
43, 391, 93, 122

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

5 x 43 x 391 x 93 x 122 = 953801490

Therefore, the lowest common multiple of 215,391,465,122 is 953801490.

LCM Formula to Find Lowest Common Multiple of 215,391,465,122

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.

215 x 391 x 465 x 122 = 4769007450

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.

215 : 1, 5, 43, 215

391 : 1, 17, 23, 391

465 : 1, 3, 5, 15, 31, 93, 155, 465

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,391,465,122, is 1.

Now, the common factors can be found like this.

215:5x 43

391:17x 23

465:3x 5x 31

122:2x 61

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

5 = 5

Therefore, the value for common factors is 5.

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 = 4769007450/(1x5)

LCM = 4769007450/5

LCM = 953801490

Thus, we can understand that the LCM of 215,391,465,122 is 953801490.
