Given numbers are 978,140,793

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

The LCM of 978,140,793 is 54288780.

Find LCM of 978,140,793 with Prime Factorization

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

2 x 489 x 70 x 793 = 54288780

Therefore, the lowest common multiple of 978,140,793 is 54288780.

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.

978 x 140 x 793 = 108577560

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.

978 : 1, 2, 3, 6, 163, 326, 489, 978

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

793 : 1, 13, 61, 793

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,140,793, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

140:2x 2x 5x 7

793:13x 61

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 = 108577560/(1x2)

LCM = 108577560/2

LCM = 54288780

Thus, we can understand that the LCM of 978,140,793 is 54288780.

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