Given numbers are 780,432,620,194

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

The LCM of 780,432,620,194 is 84436560.

Find LCM of 780,432,620,194 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 36 x 31 x 97 = 84436560

Therefore, the lowest common multiple of 780,432,620,194 is 84436560.

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 432 x 620 x 194 = 40529548800

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

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

194 : 1, 2, 97, 194

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,432,620,194, is 2.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

432:2x 2x 2x 2x 3x 3x 3

620:2x 2x 5x 31

194:2x 97

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 2x 3x 5 = 240

Therefore, the value for common factors is 240.

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 = 40529548800/(2x240)

LCM = 40529548800/480

LCM = 84436560

Thus, we can understand that the LCM of 780,432,620,194 is 84436560.
