Calculate the LCM of 726,190,445,620

Given numbers are 726,190,445,620

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

The LCM of 726,190,445,620 is 380576460.

Find LCM of 726,190,445,620 with Prime Factorization


2 726, 190, 445, 620
5 363, 95, 445, 310
363, 19, 89, 62

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

2 x 5 x 363 x 19 x 89 x 62 = 380576460

Therefore, the lowest common multiple of 726,190,445,620 is 380576460.

LCM Formula to Find Lowest Common Multiple of 726,190,445,620

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.

726 x 190 x 445 x 620 = 38057646000

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.

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

190 : 1, 2, 5, 10, 19, 38, 95, 190

445 : 1, 5, 89, 445

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,190,445,620, is 1.

Now, the common factors can be found like this.

726:2x 3x 11x 11

190:2x 5x 19

445:5x 89

620:2x 2x 5x 31

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 = 38057646000/(1x100)

LCM = 38057646000/100

LCM = 380576460

Thus, we can understand that the LCM of 726,190,445,620 is 380576460.
