Calculate the LCM of 760,621,805,578

Given numbers are 760,621,805,578

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

The LCM of 760,621,805,578 is 954775080.

Find LCM of 760,621,805,578 with Prime Factorization


2 760, 621, 805, 578
5 380, 621, 805, 289
23 76, 621, 161, 289
76, 27, 7, 289

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

2 x 5 x 23 x 76 x 27 x 7 x 289 = 954775080

Therefore, the lowest common multiple of 760,621,805,578 is 954775080.

LCM Formula to Find Lowest Common Multiple of 760,621,805,578

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.

760 x 621 x 805 x 578 = 219598268400

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.

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

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

805 : 1, 5, 7, 23, 35, 115, 161, 805

578 : 1, 2, 17, 34, 289, 578

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,621,805,578, is 1.

Now, the common factors can be found like this.

760:2x 2x 2x 5x 19

621:3x 3x 3x 23

805:5x 7x 23

578:2x 17x 17

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

2x 5x 23 = 230

Therefore, the value for common factors is 230.

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 = 219598268400/(1x230)

LCM = 219598268400/230

LCM = 954775080

Thus, we can understand that the LCM of 760,621,805,578 is 954775080.
