Calculate the LCM of 775,732,253,457,442

Given numbers are 775,732,253,457,442

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

The LCM of 775,732,253,457,442 is 14495786319300.

Find LCM of 775,732,253,457,442 with Prime Factorization


2 775, 732, 253, 457, 442
775, 366, 253, 457, 221

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

2 x 775 x 366 x 253 x 457 x 221 = 14495786319300

Therefore, the lowest common multiple of 775,732,253,457,442 is 14495786319300.

LCM Formula to Find Lowest Common Multiple of 775,732,253,457,442

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.

775 x 732 x 253 x 457 x 442 = 28991572638600

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.

775 : 1, 5, 25, 31, 155, 775

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

253 : 1, 11, 23, 253

457 : 1, 457

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,732,253,457,442, is 1.

Now, the common factors can be found like this.

775:5x 5x 31

732:2x 2x 3x 61

253:11x 23

457:457

442:2x 13x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 28991572638600/(1x2)

LCM = 28991572638600/2

LCM = 14495786319300

Thus, we can understand that the LCM of 775,732,253,457,442 is 14495786319300.
