Given numbers are 780,542,894,722

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

The LCM of 780,542,894,722 is 11369918820.

Find LCM of 780,542,894,722 with Prime Factorization

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

2 x 3 x 130 x 271 x 149 x 361 = 11369918820

Therefore, the lowest common multiple of 780,542,894,722 is 11369918820.

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 542 x 894 x 722 = 272878051680

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

542 : 1, 2, 271, 542

894 : 1, 2, 3, 6, 149, 298, 447, 894

722 : 1, 2, 19, 38, 361, 722

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,542,894,722, is 2.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

542:2x 271

894:2x 3x 149

722:2x 19x 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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 272878051680/(2x12)

LCM = 272878051680/24

LCM = 11369918820

Thus, we can understand that the LCM of 780,542,894,722 is 11369918820.
