Calculate the LCM of 140,556,781,523

Given numbers are 140,556,781,523

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

The LCM of 140,556,781,523 is 7948689980.

Find LCM of 140,556,781,523 with Prime Factorization


2 140, 556, 781, 523
2 70, 278, 781, 523
35, 139, 781, 523

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

2 x 2 x 35 x 139 x 781 x 523 = 7948689980

Therefore, the lowest common multiple of 140,556,781,523 is 7948689980.

LCM Formula to Find Lowest Common Multiple of 140,556,781,523

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.

140 x 556 x 781 x 523 = 31794759920

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.

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

556 : 1, 2, 4, 139, 278, 556

781 : 1, 11, 71, 781

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,556,781,523, is 1.

Now, the common factors can be found like this.

140:2x 2x 5x 7

556:2x 2x 139

781:11x 71

523:523

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 31794759920/(1x4)

LCM = 31794759920/4

LCM = 7948689980

Thus, we can understand that the LCM of 140,556,781,523 is 7948689980.
