Calculate the LCM of 380,898,397,570

Given numbers are 380,898,397,570

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

The LCM of 380,898,397,570 is 203208420.

Find LCM of 380,898,397,570 with Prime Factorization


2 380, 898, 397, 570
5 190, 449, 397, 285
19 38, 449, 397, 57
2, 449, 397, 3

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

2 x 5 x 19 x 2 x 449 x 397 x 3 = 203208420

Therefore, the lowest common multiple of 380,898,397,570 is 203208420.

LCM Formula to Find Lowest Common Multiple of 380,898,397,570

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.

380 x 898 x 397 x 570 = 77219199600

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.

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

898 : 1, 2, 449, 898

397 : 1, 397

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,898,397,570, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

898:2x 449

397:397

570:2x 3x 5x 19

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

2x 2x 5x 19 = 380

Therefore, the value for common factors is 380.

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 = 77219199600/(1x380)

LCM = 77219199600/380

LCM = 203208420

Thus, we can understand that the LCM of 380,898,397,570 is 203208420.
