Given numbers are 861,970,473,803,979

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

The LCM of 861,970,473,803,979 is 2566545058770.

Find LCM of 861,970,473,803,979 with Prime Factorization

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

11 x 861 x 970 x 43 x 73 x 89 = 2566545058770

Therefore, the lowest common multiple of 861,970,473,803,979 is 2566545058770.

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.

861 x 970 x 473 x 803 x 979 = 310551952111170

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

970 : 1, 2, 5, 10, 97, 194, 485, 970

473 : 1, 11, 43, 473

803 : 1, 11, 73, 803

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,970,473,803,979, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

970:2x 5x 97

473:11x 43

803:11x 73

979:11x 89

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 310551952111170/(1x121)

LCM = 310551952111170/121

LCM = 2566545058770

Thus, we can understand that the LCM of 861,970,473,803,979 is 2566545058770.
