Calculate the LCM of 103,685,795,721

Given numbers are 103,685,795,721

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

The LCM of 103,685,795,721 is 78527715.

Find LCM of 103,685,795,721 with Prime Factorization


5 103, 685, 795, 721
103 103, 137, 159, 721
1, 137, 159, 7

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

5 x 103 x 1 x 137 x 159 x 7 = 78527715

Therefore, the lowest common multiple of 103,685,795,721 is 78527715.

LCM Formula to Find Lowest Common Multiple of 103,685,795,721

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.

103 x 685 x 795 x 721 = 40441773225

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.

103 : 1, 103

685 : 1, 5, 137, 685

795 : 1, 3, 5, 15, 53, 159, 265, 795

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,685,795,721, is 1.

Now, the common factors can be found like this.

103:103

685:5x 137

795:3x 5x 53

721:7x 103

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

5x 103 = 515

Therefore, the value for common factors is 515.

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 = 40441773225/(1x515)

LCM = 40441773225/515

LCM = 78527715

Thus, we can understand that the LCM of 103,685,795,721 is 78527715.
