Calculate the LCM of 991,305,340,453,633

Given numbers are 991,305,340,453,633

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

The LCM of 991,305,340,453,633 is 1964549897220.

Find LCM of 991,305,340,453,633 with Prime Factorization


3 991, 305, 340, 453, 633
5 991, 305, 340, 151, 211
991, 61, 68, 151, 211

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

3 x 5 x 991 x 61 x 68 x 151 x 211 = 1964549897220

Therefore, the lowest common multiple of 991,305,340,453,633 is 1964549897220.

LCM Formula to Find Lowest Common Multiple of 991,305,340,453,633

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.

991 x 305 x 340 x 453 x 633 = 29468248458300

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.

991 : 1, 991

305 : 1, 5, 61, 305

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

453 : 1, 3, 151, 453

633 : 1, 3, 211, 633

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,305,340,453,633, is 1.

Now, the common factors can be found like this.

991:991

305:5x 61

340:2x 2x 5x 17

453:3x 151

633:3x 211

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 29468248458300/(1x15)

LCM = 29468248458300/15

LCM = 1964549897220

Thus, we can understand that the LCM of 991,305,340,453,633 is 1964549897220.
