Calculate the LCM of 361,670,215,345,389

Given numbers are 361,670,215,345,389

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

The LCM of 361,670,215,345,389 is 279157404810.

Find LCM of 361,670,215,345,389 with Prime Factorization


5 361, 670, 215, 345, 389
361, 134, 43, 69, 389

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

5 x 361 x 134 x 43 x 69 x 389 = 279157404810

Therefore, the lowest common multiple of 361,670,215,345,389 is 279157404810.

LCM Formula to Find Lowest Common Multiple of 361,670,215,345,389

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.

361 x 670 x 215 x 345 x 389 = 6978935120250

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.

361 : 1, 19, 361

670 : 1, 2, 5, 10, 67, 134, 335, 670

215 : 1, 5, 43, 215

345 : 1, 3, 5, 15, 23, 69, 115, 345

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,670,215,345,389, is 1.

Now, the common factors can be found like this.

361:19x 19

670:2x 5x 67

215:5x 43

345:3x 5x 23

389:389

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 6978935120250/(1x25)

LCM = 6978935120250/25

LCM = 279157404810

Thus, we can understand that the LCM of 361,670,215,345,389 is 279157404810.
