Calculate the LCM of 925,974,170,631,639

Given numbers are 925,974,170,631,639

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

The LCM of 925,974,170,631,639 is 6175609525350.

Find LCM of 925,974,170,631,639 with Prime Factorization


2 925, 974, 170, 631, 639
5 925, 487, 85, 631, 639
185, 487, 17, 631, 639

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

2 x 5 x 185 x 487 x 17 x 631 x 639 = 6175609525350

Therefore, the lowest common multiple of 925,974,170,631,639 is 6175609525350.

LCM Formula to Find Lowest Common Multiple of 925,974,170,631,639

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.

925 x 974 x 170 x 631 x 639 = 61756095253500

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.

925 : 1, 5, 25, 37, 185, 925

974 : 1, 2, 487, 974

170 : 1, 2, 5, 10, 17, 34, 85, 170

631 : 1, 631

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 925,974,170,631,639, is 1.

Now, the common factors can be found like this.

925:5x 5x 37

974:2x 487

170:2x 5x 17

631:631

639:3x 3x 71

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 61756095253500/(1x10)

LCM = 61756095253500/10

LCM = 6175609525350

Thus, we can understand that the LCM of 925,974,170,631,639 is 6175609525350.
