Calculate the LCM of 105,796,407,987

Given numbers are 105,796,407,987

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

The LCM of 105,796,407,987 is 1598801820.

Find LCM of 105,796,407,987 with Prime Factorization


3 105, 796, 407, 987
7 35, 796, 407, 329
5, 796, 407, 47

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

3 x 7 x 5 x 796 x 407 x 47 = 1598801820

Therefore, the lowest common multiple of 105,796,407,987 is 1598801820.

LCM Formula to Find Lowest Common Multiple of 105,796,407,987

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 796 x 407 x 987 = 33574838220

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

796 : 1, 2, 4, 199, 398, 796

407 : 1, 11, 37, 407

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 105,796,407,987, is 1.

Now, the common factors can be found like this.

105:3x 5x 7

796:2x 2x 199

407:11x 37

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.

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 33574838220/(1x21)

LCM = 33574838220/21

LCM = 1598801820

Thus, we can understand that the LCM of 105,796,407,987 is 1598801820.
