Given numbers are 345,763,409,678

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

The LCM of 345,763,409,678 is 24331863990.

Find LCM of 345,763,409,678 with Prime Factorization

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

3 x 115 x 763 x 409 x 226 = 24331863990

Therefore, the lowest common multiple of 345,763,409,678 is 24331863990.

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.

345 x 763 x 409 x 678 = 72995591970

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

763 : 1, 7, 109, 763

409 : 1, 409

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,763,409,678, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

763:7x 109

409:409

678:2x 3x 113

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

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 = 72995591970/(1x3)

LCM = 72995591970/3

LCM = 24331863990

Thus, we can understand that the LCM of 345,763,409,678 is 24331863990.
