Calculate the LCM of 905,320,492,712

Given numbers are 905,320,492,712

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

The LCM of 905,320,492,712 is 634050240.

Find LCM of 905,320,492,712 with Prime Factorization


2 905, 320, 492, 712
2 905, 160, 246, 356
2 905, 80, 123, 178
5 905, 40, 123, 89
181, 8, 123, 89

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

2 x 2 x 2 x 5 x 181 x 8 x 123 x 89 = 634050240

Therefore, the lowest common multiple of 905,320,492,712 is 634050240.

LCM Formula to Find Lowest Common Multiple of 905,320,492,712

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.

905 x 320 x 492 x 712 = 101448038400

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.

905 : 1, 5, 181, 905

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

712 : 1, 2, 4, 8, 89, 178, 356, 712

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,320,492,712, is 1.

Now, the common factors can be found like this.

905:5x 181

320:2x 2x 2x 2x 2x 2x 5

492:2x 2x 3x 41

712:2x 2x 2x 89

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

2x 2x 2x 2x 2x 5 = 160

Therefore, the value for common factors is 160.

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 = 101448038400/(1x160)

LCM = 101448038400/160

LCM = 634050240

Thus, we can understand that the LCM of 905,320,492,712 is 634050240.
