Given numbers are 978,971,812

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

The LCM of 978,971,812 is 385553028.

Find LCM of 978,971,812 with Prime Factorization

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

2 x 489 x 971 x 406 = 385553028

Therefore, the lowest common multiple of 978,971,812 is 385553028.

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 971 x 812 = 771106056

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

971 : 1, 971

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,971,812, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

971:971

812:2x 2x 7x 29

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 = 771106056/(1x2)

LCM = 771106056/2

LCM = 385553028

Thus, we can understand that the LCM of 978,971,812 is 385553028.

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

• LCM of 900, 600, 547
