Given numbers are 678,709,245,709

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

The LCM of 678,709,245,709 is 117771990.

Find LCM of 678,709,245,709 with Prime Factorization

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

709 x 678 x 1 x 245 x 1 = 117771990

Therefore, the lowest common multiple of 678,709,245,709 is 117771990.

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.

678 x 709 x 245 x 709 = 83500340910

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.

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

709 : 1, 709

245 : 1, 5, 7, 35, 49, 245

709 : 1, 709

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,709,245,709, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

709:709

245:5x 7x 7

709:709

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

709 = 709

Therefore, the value for common factors is 709.

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 = 83500340910/(1x709)

LCM = 83500340910/709

LCM = 117771990

Thus, we can understand that the LCM of 678,709,245,709 is 117771990.
