Given numbers are 631,666,780

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

The LCM of 631,666,780 is 54631980.

Find LCM of 631,666,780 with Prime Factorization

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

2 x 3 x 631 x 111 x 130 = 54631980

Therefore, the lowest common multiple of 631,666,780 is 54631980.

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 666 x 780 = 327791880

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

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,666,780, is 1.

Now, the common factors can be found like this.

631:631

666:2x 3x 3x 37

780:2x 2x 3x 5x 13

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 327791880/(1x6)

LCM = 327791880/6

LCM = 54631980

Thus, we can understand that the LCM of 631,666,780 is 54631980.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 306, 687, 122
