Calculate the LCM of 309,562,440,321

Given numbers are 309,562,440,321

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

The LCM of 309,562,440,321 is 4087909320.

Find LCM of 309,562,440,321 with Prime Factorization


2 309, 562, 440, 321
3 309, 281, 220, 321
103, 281, 220, 107

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

2 x 3 x 103 x 281 x 220 x 107 = 4087909320

Therefore, the lowest common multiple of 309,562,440,321 is 4087909320.

LCM Formula to Find Lowest Common Multiple of 309,562,440,321

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.

309 x 562 x 440 x 321 = 24527455920

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.

309 : 1, 3, 103, 309

562 : 1, 2, 281, 562

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,562,440,321, is 1.

Now, the common factors can be found like this.

309:3x 103

562:2x 281

440:2x 2x 2x 5x 11

321:3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 24527455920/(1x6)

LCM = 24527455920/6

LCM = 4087909320

Thus, we can understand that the LCM of 309,562,440,321 is 4087909320.
