Calculate the LCM of 771,735,543,140

Given numbers are 771,735,543,140

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

The LCM of 771,735,543,140 is 136759980.

Find LCM of 771,735,543,140 with Prime Factorization


3 771, 735, 543, 140
5 257, 245, 181, 140
7 257, 49, 181, 28
257, 7, 181, 4

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

3 x 5 x 7 x 257 x 7 x 181 x 4 = 136759980

Therefore, the lowest common multiple of 771,735,543,140 is 136759980.

LCM Formula to Find Lowest Common Multiple of 771,735,543,140

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.

771 x 735 x 543 x 140 = 43079393700

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.

771 : 1, 3, 257, 771

735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735

543 : 1, 3, 181, 543

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,735,543,140, is 1.

Now, the common factors can be found like this.

771:3x 257

735:3x 5x 7x 7

543:3x 181

140:2x 2x 5x 7

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

3x 3x 5x 7 = 315

Therefore, the value for common factors is 315.

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 = 43079393700/(1x315)

LCM = 43079393700/315

LCM = 136759980

Thus, we can understand that the LCM of 771,735,543,140 is 136759980.
