Given numbers are 805,706,122,987

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

The LCM of 805,706,122,987 is 4888206330.

Find LCM of 805,706,122,987 with Prime Factorization

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

2 x 7 x 115 x 353 x 61 x 141 = 4888206330

Therefore, the lowest common multiple of 805,706,122,987 is 4888206330.

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.

805 x 706 x 122 x 987 = 68434888620

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.

805 : 1, 5, 7, 23, 35, 115, 161, 805

706 : 1, 2, 353, 706

122 : 1, 2, 61, 122

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,706,122,987, is 1.

Now, the common factors can be found like this.

805:5x 7x 23

706:2x 353

122:2x 61

987:3x 7x 47

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 68434888620/(1x14)

LCM = 68434888620/14

LCM = 4888206330

Thus, we can understand that the LCM of 805,706,122,987 is 4888206330.
