Calculate the LCM of 690,857,611,742

Given numbers are 690,857,611,742

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

The LCM of 690,857,611,742 is 134043275730.

Find LCM of 690,857,611,742 with Prime Factorization


2 690, 857, 611, 742
345, 857, 611, 371

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

2 x 345 x 857 x 611 x 371 = 134043275730

Therefore, the lowest common multiple of 690,857,611,742 is 134043275730.

LCM Formula to Find Lowest Common Multiple of 690,857,611,742

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 857 x 611 x 742 = 268086551460

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

857 : 1, 857

611 : 1, 13, 47, 611

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,857,611,742, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

857:857

611:13x 47

742:2x 7x 53

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

2 = 2

Therefore, the value for common factors is 2.

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 = 268086551460/(1x2)

LCM = 268086551460/2

LCM = 134043275730

Thus, we can understand that the LCM of 690,857,611,742 is 134043275730.
