Given numbers are 780,770,473,578,605

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

The LCM of 780,770,473,578,605 is 8210021820.

Find LCM of 780,770,473,578,605 with Prime Factorization

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

2 x 5 x 11 x 78 x 7 x 43 x 289 x 11 = 8210021820

Therefore, the lowest common multiple of 780,770,473,578,605 is 8210021820.

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 770 x 473 x 578 x 605 = 99341264022000

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

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

473 : 1, 11, 43, 473

578 : 1, 2, 17, 34, 289, 578

605 : 1, 5, 11, 55, 121, 605

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,770,473,578,605, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

770:2x 5x 7x 11

473:11x 43

578:2x 17x 17

605:5x 11x 11

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 5x 5x 11x 11 = 12100

Therefore, the value for common factors is 12100.

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 = 99341264022000/(1x12100)

LCM = 99341264022000/12100

LCM = 8210021820

Thus, we can understand that the LCM of 780,770,473,578,605 is 8210021820.
