Calculate the LCM of 643,563,720,116

Given numbers are 643,563,720,116

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

The LCM of 643,563,720,116 is 7558747920.

Find LCM of 643,563,720,116 with Prime Factorization


2 643, 563, 720, 116
2 643, 563, 360, 58
643, 563, 180, 29

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

2 x 2 x 643 x 563 x 180 x 29 = 7558747920

Therefore, the lowest common multiple of 643,563,720,116 is 7558747920.

LCM Formula to Find Lowest Common Multiple of 643,563,720,116

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.

643 x 563 x 720 x 116 = 30234991680

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.

643 : 1, 643

563 : 1, 563

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

116 : 1, 2, 4, 29, 58, 116

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,563,720,116, is 1.

Now, the common factors can be found like this.

643:643

563:563

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

116:2x 2x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 30234991680/(1x4)

LCM = 30234991680/4

LCM = 7558747920

Thus, we can understand that the LCM of 643,563,720,116 is 7558747920.
