Calculate the LCM of 798,387,611,140

Given numbers are 798,387,611,140

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

The LCM of 798,387,611,140 is 628975620.

Find LCM of 798,387,611,140 with Prime Factorization


2 798, 387, 611, 140
3 399, 387, 611, 70
7 133, 129, 611, 70
19, 129, 611, 10

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

2 x 3 x 7 x 19 x 129 x 611 x 10 = 628975620

Therefore, the lowest common multiple of 798,387,611,140 is 628975620.

LCM Formula to Find Lowest Common Multiple of 798,387,611,140

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.

798 x 387 x 611 x 140 = 26416976040

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

387 : 1, 3, 9, 43, 129, 387

611 : 1, 13, 47, 611

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 798,387,611,140, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

387:3x 3x 43

611:13x 47

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.

2x 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 26416976040/(1x42)

LCM = 26416976040/42

LCM = 628975620

Thus, we can understand that the LCM of 798,387,611,140 is 628975620.
