Given numbers are 692,378,542,646,784

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

The LCM of 692,378,542,646,784 is 320551448112.

Find LCM of 692,378,542,646,784 with Prime Factorization

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

2 x 2 x 7 x 173 x 27 x 271 x 323 x 28 = 320551448112

Therefore, the lowest common multiple of 692,378,542,646,784 is 320551448112.

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.

692 x 378 x 542 x 646 x 784 = 71803524377088

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.

692 : 1, 2, 4, 173, 346, 692

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

542 : 1, 2, 271, 542

646 : 1, 2, 17, 19, 34, 38, 323, 646

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,378,542,646,784, is 2.

Now, the common factors can be found like this.

692:2x 2x 173

378:2x 3x 3x 3x 7

542:2x 271

646:2x 17x 19

784:2x 2x 2x 2x 7x 7

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 7 = 112

Therefore, the value for common factors is 112.

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 = 71803524377088/(2x112)

LCM = 71803524377088/224

LCM = 320551448112

Thus, we can understand that the LCM of 692,378,542,646,784 is 320551448112.
