Calculate the LCM of 631,642,469,175,484

Given numbers are 631,642,469,175,484

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

The LCM of 631,642,469,175,484 is 1149456669900.

Find LCM of 631,642,469,175,484 with Prime Factorization


2 631, 642, 469, 175, 484
7 631, 321, 469, 175, 242
631, 321, 67, 25, 242

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

2 x 7 x 631 x 321 x 67 x 25 x 242 = 1149456669900

Therefore, the lowest common multiple of 631,642,469,175,484 is 1149456669900.

LCM Formula to Find Lowest Common Multiple of 631,642,469,175,484

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.

631 x 642 x 469 x 175 x 484 = 16092393378600

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.

631 : 1, 631

642 : 1, 2, 3, 6, 107, 214, 321, 642

469 : 1, 7, 67, 469

175 : 1, 5, 7, 25, 35, 175

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,642,469,175,484, is 1.

Now, the common factors can be found like this.

631:631

642:2x 3x 107

469:7x 67

175:5x 5x 7

484:2x 2x 11x 11

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 16092393378600/(1x14)

LCM = 16092393378600/14

LCM = 1149456669900

Thus, we can understand that the LCM of 631,642,469,175,484 is 1149456669900.
