Given numbers are 780,978,237,606,273

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

The LCM of 780,978,237,606,273 is 7101150420.

Find LCM of 780,978,237,606,273 with Prime Factorization

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

2 x 3 x 13 x 10 x 163 x 79 x 101 x 7 = 7101150420

Therefore, the lowest common multiple of 780,978,237,606,273 is 7101150420.

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 978 x 237 x 606 x 273 = 29910045569040

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

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

237 : 1, 3, 79, 237

606 : 1, 2, 3, 6, 101, 202, 303, 606

273 : 1, 3, 7, 13, 21, 39, 91, 273

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,978,237,606,273, is 3.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

978:2x 3x 163

237:3x 79

606:2x 3x 101

273:3x 7x 13

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 3x 3x 3x 13 = 1404

Therefore, the value for common factors is 1404.

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 = 29910045569040/(3x1404)

LCM = 29910045569040/4212

LCM = 7101150420

Thus, we can understand that the LCM of 780,978,237,606,273 is 7101150420.
