Calculate the LCM of 621,743,966,892

Given numbers are 621,743,966,892

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

The LCM of 621,743,966,892 is 2881000332.

Find LCM of 621,743,966,892 with Prime Factorization


2 621, 743, 966, 892
3 621, 743, 483, 446
23 207, 743, 161, 446
9, 743, 7, 446

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

2 x 3 x 23 x 9 x 743 x 7 x 446 = 2881000332

Therefore, the lowest common multiple of 621,743,966,892 is 2881000332.

LCM Formula to Find Lowest Common Multiple of 621,743,966,892

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 743 x 966 x 892 = 397578045816

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

743 : 1, 743

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

892 : 1, 2, 4, 223, 446, 892

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,743,966,892, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

743:743

966:2x 3x 7x 23

892:2x 2x 223

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

2x 3x 23 = 138

Therefore, the value for common factors is 138.

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 = 397578045816/(1x138)

LCM = 397578045816/138

LCM = 2881000332

Thus, we can understand that the LCM of 621,743,966,892 is 2881000332.
