Calculate the LCM of 380,331,695,720

Given numbers are 380,331,695,720

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

The LCM of 380,331,695,720 is 629403120.

Find LCM of 380,331,695,720 with Prime Factorization


2 380, 331, 695, 720
2 190, 331, 695, 360
5 95, 331, 695, 180
19, 331, 139, 36

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

2 x 2 x 5 x 19 x 331 x 139 x 36 = 629403120

Therefore, the lowest common multiple of 380,331,695,720 is 629403120.

LCM Formula to Find Lowest Common Multiple of 380,331,695,720

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 331 x 695 x 720 = 62940312000

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

331 : 1, 331

695 : 1, 5, 139, 695

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,331,695,720, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

331:331

695:5x 139

720:2x 2x 2x 2x 3x 3x 5

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 5 = 100

Therefore, the value for common factors is 100.

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 = 62940312000/(1x100)

LCM = 62940312000/100

LCM = 629403120

Thus, we can understand that the LCM of 380,331,695,720 is 629403120.
