Given numbers are 844,780,603,211,978

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

The LCM of 844,780,603,211,978 is 5392134540.

Find LCM of 844,780,603,211,978 with Prime Factorization

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

2 x 2 x 3 x 211 x 1 x 65 x 201 x 1 x 163 = 5392134540

Therefore, the lowest common multiple of 844,780,603,211,978 is 5392134540.

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.

844 x 780 x 603 x 211 x 978 = 81917307931680

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.

844 : 1, 2, 4, 211, 422, 844

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

603 : 1, 3, 9, 67, 201, 603

211 : 1, 211

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,780,603,211,978, is 1.

Now, the common factors can be found like this.

844:2x 2x 211

780:2x 2x 3x 5x 13

603:3x 3x 67

211:211

978:2x 3x 163

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 2x 3x 3x 211 = 15192

Therefore, the value for common factors is 15192.

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 = 81917307931680/(1x15192)

LCM = 81917307931680/15192

LCM = 5392134540

Thus, we can understand that the LCM of 844,780,603,211,978 is 5392134540.
