Given numbers are 780,702,477,741

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

The LCM of 780,702,477,741 is 7069140.

Find LCM of 780,702,477,741 with Prime Factorization

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

2 x 3 x 3 x 13 x 10 x 3 x 53 x 19 = 7069140

Therefore, the lowest common multiple of 780,702,477,741 is 7069140.

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.

780 x 702 x 477 x 741 = 193538914920

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

477 : 1, 3, 9, 53, 159, 477

741 : 1, 3, 13, 19, 39, 57, 247, 741

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,702,477,741, is 3.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

702:2x 3x 3x 3x 13

477:3x 3x 53

741:3x 13x 19

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 3x 3x 13x 13 = 9126

Therefore, the value for common factors is 9126.

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 = 193538914920/(3x9126)

LCM = 193538914920/27378

LCM = 7069140

Thus, we can understand that the LCM of 780,702,477,741 is 7069140.
