Given numbers are 979,862,310,621

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

The LCM of 979,862,310,621 is 81229401990.

Find LCM of 979,862,310,621 with Prime Factorization

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

2 x 979 x 431 x 155 x 621 = 81229401990

Therefore, the lowest common multiple of 979,862,310,621 is 81229401990.

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.

979 x 862 x 310 x 621 = 162458803980

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.

979 : 1, 11, 89, 979

862 : 1, 2, 431, 862

310 : 1, 2, 5, 10, 31, 62, 155, 310

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,862,310,621, is 1.

Now, the common factors can be found like this.

979:11x 89

862:2x 431

310:2x 5x 31

621:3x 3x 3x 23

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 = 162458803980/(1x2)

LCM = 162458803980/2

LCM = 81229401990

Thus, we can understand that the LCM of 979,862,310,621 is 81229401990.
