Find LCM of 105,806,549,682,978 with Prime Factorization


2 105, 806, 549, 682, 978
3 105, 403, 549, 341, 489
31 35, 403, 183, 341, 163
35, 13, 183, 11, 163

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

2 x 3 x 31 x 35 x 13 x 183 x 11 x 163 = 27768710970

Therefore, the lowest common multiple of 105,806,549,682,978 is 27768710970.

LCM Formula to Find Lowest Common Multiple of 105,806,549,682,978

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.

105 x 806 x 549 x 682 x 978 = 30989881442520

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.

105 : 1, 3, 5, 7, 15, 21, 35, 105

806 : 1, 2, 13, 26, 31, 62, 403, 806

549 : 1, 3, 9, 61, 183, 549

682 : 1, 2, 11, 22, 31, 62, 341, 682

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,806,549,682,978, is 1.

Now, the common factors can be found like this.

105:3x 5x 7

806:2x 13x 31

549:3x 3x 61

682:2x 11x 31

978:2x 3x 163

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

2x 2x 3x 3x 31 = 1116

Therefore, the value for common factors is 1116.

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 = 30989881442520/(1x1116)

LCM = 30989881442520/1116

LCM = 27768710970

Thus, we can understand that the LCM of 105,806,549,682,978 is 27768710970.
