Calculate the LCM of 785,578,690,682

Given numbers are 785,578,690,682

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

The LCM of 785,578,690,682 is 10675813170.

Find LCM of 785,578,690,682 with Prime Factorization


2 785, 578, 690, 682
5 785, 289, 345, 341
157, 289, 69, 341

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

2 x 5 x 157 x 289 x 69 x 341 = 10675813170

Therefore, the lowest common multiple of 785,578,690,682 is 10675813170.

LCM Formula to Find Lowest Common Multiple of 785,578,690,682

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.

785 x 578 x 690 x 682 = 213516263400

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.

785 : 1, 5, 157, 785

578 : 1, 2, 17, 34, 289, 578

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

682 : 1, 2, 11, 22, 31, 62, 341, 682

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,578,690,682, is 1.

Now, the common factors can be found like this.

785:5x 157

578:2x 17x 17

690:2x 3x 5x 23

682:2x 11x 31

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 213516263400/(1x20)

LCM = 213516263400/20

LCM = 10675813170

Thus, we can understand that the LCM of 785,578,690,682 is 10675813170.
