Calculate the LCM of 690,782,379,845

Given numbers are 690,782,379,845

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

The LCM of 690,782,379,845 is 751318230.

Find LCM of 690,782,379,845 with Prime Factorization


2 690, 782, 379, 845
5 345, 391, 379, 845
23 69, 391, 379, 169
3, 17, 379, 169

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

2 x 5 x 23 x 3 x 17 x 379 x 169 = 751318230

Therefore, the lowest common multiple of 690,782,379,845 is 751318230.

LCM Formula to Find Lowest Common Multiple of 690,782,379,845

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.

690 x 782 x 379 x 845 = 172803192900

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

782 : 1, 2, 17, 23, 34, 46, 391, 782

379 : 1, 379

845 : 1, 5, 13, 65, 169, 845

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,782,379,845, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

782:2x 17x 23

379:379

845:5x 13x 13

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

2x 5x 23 = 230

Therefore, the value for common factors is 230.

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 = 172803192900/(1x230)

LCM = 172803192900/230

LCM = 751318230

Thus, we can understand that the LCM of 690,782,379,845 is 751318230.
