Given numbers are 722,121,782,517

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

The LCM of 722,121,782,517 is 1605451474.

Find LCM of 722,121,782,517 with Prime Factorization

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

2 x 11 x 361 x 11 x 391 x 47 = 1605451474

Therefore, the lowest common multiple of 722,121,782,517 is 1605451474.

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.

722 x 121 x 782 x 517 = 35319932428

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.

722 : 1, 2, 19, 38, 361, 722

121 : 1, 11, 121

782 : 1, 2, 17, 23, 34, 46, 391, 782

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,121,782,517, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

121:11x 11

782:2x 17x 23

517:11x 47

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 35319932428/(1x22)

LCM = 35319932428/22

LCM = 1605451474

Thus, we can understand that the LCM of 722,121,782,517 is 1605451474.
