Given numbers are 842,959,780

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

The LCM of 842,959,780 is 314916420.

Find LCM of 842,959,780 with Prime Factorization

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

2 x 421 x 959 x 390 = 314916420

Therefore, the lowest common multiple of 842,959,780 is 314916420.

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.

842 x 959 x 780 = 629832840

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.

842 : 1, 2, 421, 842

959 : 1, 7, 137, 959

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,959,780, is 1.

Now, the common factors can be found like this.

842:2x 421

959:7x 137

780:2x 2x 3x 5x 13

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 = 629832840/(1x2)

LCM = 629832840/2

LCM = 314916420

Thus, we can understand that the LCM of 842,959,780 is 314916420.
