Calculate the LCM of 862,605,320,477

Given numbers are 862,605,320,477

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

The LCM of 862,605,320,477 is 7960328640.

Find LCM of 862,605,320,477 with Prime Factorization


2 862, 605, 320, 477
5 431, 605, 160, 477
431, 121, 32, 477

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

2 x 5 x 431 x 121 x 32 x 477 = 7960328640

Therefore, the lowest common multiple of 862,605,320,477 is 7960328640.

LCM Formula to Find Lowest Common Multiple of 862,605,320,477

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.

862 x 605 x 320 x 477 = 79603286400

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.

862 : 1, 2, 431, 862

605 : 1, 5, 11, 55, 121, 605

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

477 : 1, 3, 9, 53, 159, 477

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,605,320,477, is 1.

Now, the common factors can be found like this.

862:2x 431

605:5x 11x 11

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

477:3x 3x 53

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 = 79603286400/(1x10)

LCM = 79603286400/10

LCM = 7960328640

Thus, we can understand that the LCM of 862,605,320,477 is 7960328640.
