Given numbers are 817,713,169,860

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

The LCM of 817,713,169,860 is 1968920980.

Find LCM of 817,713,169,860 with Prime Factorization

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

43 x 19 x 713 x 169 x 20 = 1968920980

Therefore, the lowest common multiple of 817,713,169,860 is 1968920980.

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.

817 x 713 x 169 x 860 = 84663602140

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.

817 : 1, 19, 43, 817

713 : 1, 23, 31, 713

169 : 1, 13, 169

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,713,169,860, is 1.

Now, the common factors can be found like this.

817:19x 43

713:23x 31

169:13x 13

860:2x 2x 5x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 84663602140/(1x43)

LCM = 84663602140/43

LCM = 1968920980

Thus, we can understand that the LCM of 817,713,169,860 is 1968920980.
