Calculate the LCM of 621,678,734

Given numbers are 621,678,734

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

The LCM of 621,678,734 is 51506982.

Find LCM of 621,678,734 with Prime Factorization


2 621, 678, 734
3 621, 339, 367
207, 113, 367

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

2 x 3 x 207 x 113 x 367 = 51506982

Therefore, the lowest common multiple of 621,678,734 is 51506982.

LCM Formula to Find Lowest Common Multiple of 621,678,734

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.

621 x 678 x 734 = 309041892

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

678 : 1, 2, 3, 6, 113, 226, 339, 678

734 : 1, 2, 367, 734

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,678,734, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

678:2x 3x 113

734:2x 367

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 = 309041892/(1x6)

LCM = 309041892/6

LCM = 51506982

Thus, we can understand that the LCM of 621,678,734 is 51506982.
