Calculate the LCM of 862,673,472,789

Given numbers are 862,673,472,789

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

The LCM of 862,673,472,789 is 108021781704.

Find LCM of 862,673,472,789 with Prime Factorization


2 862, 673, 472, 789
431, 673, 236, 789

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

2 x 431 x 673 x 236 x 789 = 108021781704

Therefore, the lowest common multiple of 862,673,472,789 is 108021781704.

LCM Formula to Find Lowest Common Multiple of 862,673,472,789

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 673 x 472 x 789 = 216043563408

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

673 : 1, 673

472 : 1, 2, 4, 8, 59, 118, 236, 472

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,673,472,789, is 1.

Now, the common factors can be found like this.

862:2x 431

673:673

472:2x 2x 2x 59

789:3x 263

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

2 = 2

Therefore, the value for common factors is 2.

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 = 216043563408/(1x2)

LCM = 216043563408/2

LCM = 108021781704

Thus, we can understand that the LCM of 862,673,472,789 is 108021781704.
